Simulation of Vibration Caused by Blasting for a Layered Slope

Recent studies showed that vibration caused by blasting mainly reflects the property of geological structure itself neighboring the blasting center. Different vibration signals can be collected for different geological structures under blasting. Hence, vibration signal can be used to identify geological structure, especial for a slope with a weak layer. As the geological structure for a practical slope is usually complicated, the simulation of vibration caused by blasting should be carried out first. Generally, the material in a certain zone near the blasting center will undergo damage, so the physical model to simulate this region is the most concerned. In this paper, the damaged zone near blasting center is neglected, and the blasting load can be considered being applied on the interface between the damaged zone and undamaged zone. Regarding the relations between the weight of explosive, the size of damaged zone, and the dynamic loading to propagate out away, the vibration caused by blasting for a practical layered slope is simulated. Compared with the measured signal in site, it can be seen that the simulating result is in well agreement with that of practical testing. The results also indicate that the farther the testing point apart from the blasting center, the more accurate the simulation is.

Effects of Microstructural Heterogeneity on The Spallation Behavior of Materials

It is of utmost importance to understand the spallation behaviour of heterogeneous materials. In this paper, a driven nonlinear threshold model with stress fluctuation is presented to study the effects of microstructural heterogeneity on continuum damage evolution. The spallation behavior of heterogeneity material is analyzed with this model. The heterogeniety of mesoscopic units is characterized in terms of Weibull modulus m of strength distibution and stress fluctuation parameter k. At high stress, the maximum damage increases with m; while at low stress, the maximum damage decreases. In addition, for low stress, severe stress fluctuation causes higher damage; while for high stress, causes lower damage.

Decada primeira (-terceira) da Asia de Jo��o de Barros : dos feitos que os portuguezes fezer��o no descobrimento & conquista dos mares & terras do Oriente : dirigida ao Senado da Camara desta cidade de Lisboa : com todas as licen��as necessarias.

Jo��o de Barros, historiador, renascentista portugu��s, nasceu por volta de 1496, provavelmente em Viseu, e morreu em 20 de outubro de 1570, na quinta de S. Louren��o, pr��ximo da Ribeira de Lit��m. Entrou para o servi��o do Rei D. Manuel desde menino, onde teve seus primeiros mestres e escreveu sua primeira obra, um romance de cavalaria, a Chronica do Imperador Clarimundo. Em 1525, foi nomeado tesoureiro e, em 1533, feitor da Casa da ��ndia, posto que lhe permitiu ter acesso a numerosas e aut��nticas fontes, tornando-se um dos historiadores mais importantes da expans��o portuguesa. Quando o governo de D. Jo��o III estabeleceu para o Brasil o regime das capitanias heredit��rias, a Jo��o de Barros e a dois associados (Aires da Cunha e Fern��o de ��lvares de Andrade) foi concedido o trato de terra que ia do Rio Grande ao Maranh��o. Em 1531, morreu Louren��o de C��ceres, que deveria escrever a hist��ria da ��ndia, e foi esta, ent��o, confiada a Jo��o de Barros, seu sobrinho. Em 1552, sa��a a primeira das D��cadas da ��sia. Al��m dos trabalhos hist��ricos , escreveu o tratado R��pica pneuma (Mercado espiritual); o Di��logo da viciosa vergonha; o Di��logo sobre preceitos morais; uma gram��tica da l��ngua portuguesa e uma cartilha para aprender a ler. Dedicou-se ��s l��nguas e ��s letras cl��ssicas, �� Geografia, �� Hist��ria e �� Cosmografia. A obra est�� assim dividida: da primeira �� quarta d��cada, por Jo��o de Barros, em oito volumes; um volume contendo a obra de Jo��o de Barros, por Manuel Severim de Faria , e o ��ndice das quatro d��cadas; da quarta �� d��cima segunda d��cada, de Diogo do Couto, em quinze volumes, a�� inclu��do o ��ndice das D��cadas de Couto. Cont��m, ainda, nas obras, retratos de Jo��o de Barros, do Infante D. Henrique e de Afonso de Albuquerque e cinco cartas geogr��ficas. Segundo Brunet, as D��cadas XI e XII parecem estar abreviadas. Classifica, tamb��m, esta como uma bela edi����o e que substitui com vantagens as anteriores. A primeira edi����o Da Asia de Jo��o de Barros e de Diogo de Couto foi publicada em Lisboa, em 1522, por Germ��o Galhardo.

Experimental Evidence of Critical Sensitivity in Catastrophe

The paper presents an experimental study on critical sensitivity in rocks. Critical sensitivity means that the response of a system to external controlling variable may become significantly sensitive as the system approaches its catastrophic rupture point. It is found that the sensitivities measured by responses on three scales (sample scale, locally macroscopic scales and mesoscopic scale) display increase prior to catastrophic transition point. These experimental results do support the concept that critical sensitivity might be a common precursory feature of catastrophe. Furthermore, our previous theoretical model is extended to explore the fluctuations in critical sensitivity in the rock tests.

Nuestros datos revelan que s��lo el 10% de auditores en ejercicio con plena responsabilidad son mujeres. Por otro lado, pretendemos analizar las causas que han propiciado esta situaci��n. Entre otros, consideramos que la formaci��n y la cultura, tanto geogr��fica como de los negocios, han sido aspectos clave. A��n as��, las empresas son conscientes de la incorporaci��n de la mujer al mercado laboral, y por tanto hay que buscar el aprovechamiento del talento, implicando y motivando a las personas y buscando nuevas estrategias.

Failure process analysis of cement under explosive loading with a generalized driven nonlinear threshold model

The microstructural heterogeneity and stress fluctuation play important roles in the failure process of brittle materials. In this paper, a generalized driven nonlinear threshold model with stress fluctuation is presented to study the effects of microstructural heterogeneity on continuum damage evolution. As an illustration, the failure process of cement material under explosive loading is analyzed using the model. The result agrees well with the experimental one, which proves the efficiency of the model.

Elastic and statistically brittle (ESB) model, damage localization and catastrophic rupture

In this paper, an elastic and statistically brittle (ESB) model is applied to the process of damage evolution induced catastrophic rupture and the influence of localization and softening on catastrophic rupture is discussed. According to the analysis, the uncertainty of catastrophic rupture should be attributed to the unknown scale of localized zone. Based on the elastic and statistically brittle model but local mean field approximation, the relation between the scale of localized zone and catastrophic rupture is obtained and then justified with experiments. These results can not only give a deeper understanding of the mechanism governing catastrophic rupture, but also provide a possible tool to foresee the occurrence of catastrophic rupture.

La estructura y propiedades magn��ticos de las nanopart��culas de Fe50Ni50 obtenidas mediante el m��todo de explosi��n el��ctrica de hilo

[Es]Actualmente ninguna ��rea cient��fica es ajena a la revoluci��n de la nanociencia; las nanopart��culas atraen el inter��s de muchos investigadores desde el punto de vista de la ciencia fundamental y para sus aplicaciones tecnol��gicas. Las nanopart��culas ofrecen la posibilidad de fabricar sensores que sean capaces de detectar desde un virus hasta concentraciones de substancias pat��genas que no pueden ser detectadas por los m��todos convencionales. Hoy en d��a existes 82 tratamientos contra el c��ncer basadas en la utilizaci��n de nanopart��culas y los materiales composite con nanopart��culas se utilizan como medio de protecci��n frente la radiaci��n del rango de microondas. En la rama de ciencias ambientales, las nanopart��culas met��licas sirven como materiales anticontaminantes. En este trabajo se ha estudiado la estructura y las propiedades magn��ticas de las nanopart��culas de FeNi preparadas mediante el m��todo de explosi��n el��ctrica de hilo. Con la t��cnica de Rayos���X(DRX) se ha determinado que las nanopart��culas se cristalizan en un sistema c��bico FCC con un par��metro de celda de 3.596 ��, tambi��n, se ha obtenido el tama��o de dominio coherente que es de 35 nm. La muestra se ha sometido a un programa de temperatura controlada para seguir la evoluci��n de la estructura cristalina y del tama��o del cristal, tanto en atm��sfera oxidante como en vac��o. Para el aprendizaje de los microscopios utilizados en este trabajo, se ha asistido al curso ���Fundamentos de microscopia electr��nica de barrido y microan��lisis��� impartido por SGIker de la UPV/EHU. Se han empleado los microscopios electr��nicos SEM y TEM para obtener im��genes de gran resoluci��n de la muestra y analizar su contenido elemental. Partiendo de las im��genes sacadas por el SEM se ha calculado el valor medio del tama��o de las part��culas de la muestra, 58 nm. Mediante el Mastersizer 2000 se ha medido el tama��o de las part��culas y/o agregados por m��todo de difracci��n l��ser, disgregando la muestra todo lo posible hasta conseguir el tama��o medio que se aproxime al de una sola part��cula, 100nm. Por ��ltimo, para la caracterizaci��n magn��tica se ha servido del VSM que mide el momento magn��tico de una muestra cuando ��sta vibra en presencia de un campo magn��tico est��tico, consiguiendo una imanaci��n de saturaci��n de 125 emu/g. Hemos fabricado y caracterizado las nanopart��culas magn��ticas de hierro-n��quel y los resultados obtenidos han sido enviados a un congreso especializado de ciencia de materiales (ISMANAM - 2013, Italia).

Adiabatic shear localization: occurrence, theories, and applications

<div id="synopsistext" dir="ltr" class="sa"><img src="http://img2.imagesbn.com/p/9780080412665_p0_v1_s260x420.gif" border="0" alt="" hspace="8" width="100" height="153" align="left" />Adiabatic shear localization is a mode of failure that occurs in dynamic loading. It is characterized by thermal softening occurring over a very narrow region of a material and is usually a precursor to ductile fracture and catastrophic failure. This reference source is the first detailed study of the mechanics and modes of adiabatic shear localization in solids, and provides a systematic description of a number of aspects of adiabatic shear banding. The inclusion of the appendices which provide a quick reference section and a comprehensive collection of thermomechanical data allows rapid access and understanding of the subject and its phenomena. The concepts and techniques described in this work can usefully be applied to solve a multitude of problems encountered by those investigating fracture and damage in materials, impact dynamics, metal working and other areas. This reference book has come about in response to the pressing demand of mechanical and metallurgical engineers for a high quality summary of the knowledge gained over the last twenty years. While fulfilling this requirement, the book is also of great interest to academics and researchers into materials performance.</div><div dir="ltr" class="sa"><h3

Eduki desberdinen kudeaketa onartuko duen sistema baten garapena. Edukiak era desberdinean agertu daitezke, bai era fisikoan (liburuak, DVDak...) edo era digitalizatuan (lainoan egondako artxiboak, youtube, linkak...). Modulo hau EVEAn (entorno virtual de ense��anza y aprendizaje) integratuko da, moodlen hain zuzen ere. PHP ingurunea erabiliko da eta datu basea kudeatzeko MySQL.
