Planteamiento experimental de la experiencia del modelado con barro en la Facultad de Formación del Profesorado durante el curso 2012-2013

[ES] Con motivo de la práctica docente universitaria en la Facultad de Formación del Profesorado con alumnos del grado de Primaria, en el ámbito de las artes plásticas, tuvimos la idea y la oportunidad de reforzar y ampliar los recursos didácticos planteados a priori en la investigación, experimentándolos con un sector más amplio que el de los alumnos de especialidades específicamente artísticas, a quienes iba dirigido en un principio la creación de recursos didácticos relacionados con la tesis titulada: “Escultura pública en Gran Canaria entre 1980-2010: recursos didácticos para la enseñanza de algunos procedimientos usados en ellas.” [EN] In the context of teaching activities to Primary Education students at the Teacher Training College in the field of plastic arts and in reference to the thesis called 1980-2012 Public Sculpture in Gran Canaria, Didactic Resources for the Teaching of some of the Procedures Applied in their Making geared towards students whose specialties were specifically artistic, we had the op ortunity to reinforce and increase the methodological resources considered within the research but with students different to those of the speciality of plastics arts.

Foil rolling : a new interpretation of experimental results

This paper explores a new interpretation of experiments on foil rolling. The assumption that the roll remains convex is relaxed so that the strip profile may become concave, or thicken in the roll gap. However, we conjecture that the concave profile is associated with phenomena which occur after the rolls have stopped. We argue that the yield criterion must be satisfied in a nonconventional manner if such a phenomenon is caused plastically. Finite element analysis on an extrusion problem appears to confirm this conjecture.

Experimental studies on comparison of microwave curing and thermal curing of epoxy resins used for alternative mould materials

In this present work attempts have been made to study the glass transition temperature of alternative mould materials by using both microwave heating and conventional oven heating. In this present work three epoxy resins, namely R2512, R2515 and R2516, which are commonly used for making injection moulds have been used in combination with two hardeners H2403 and H2409. The magnetron microwave generator used in this research is operating at a frequency of 2.45 GHz with a hollow rectangular waveguide. In order to distinguish the effects between the microwave and conventional heating, a number of experiments were performed to test their mechanical properties such as tensile and flexural strengths. Additionally, differential scanning calorimeter technique was implemented to measure the glass transition temperature on both microwave and conventional heating. This study provided necessary evidences to establish that microwave heated mould materials resulted with higher glass transition temperature than the conventional heating. Finally, attempts were also made to study the microstructure of microwave-cured materials by using a scanning electron microscope in order to analyze the morphology of cured specimens.
