Non-linear finite element analysis of thin composite structures

A non-conforming three-node triangular finite element with 18 degree of freedom, is used in conjugation with the Kirchhoff theory for the non-linear analysis of thin composite plate-shell structure. The formulation of the geometrically non-linear analysis is based on an updated Lagrangian formulation associated with the Newton-Raphson iterative technique, which incorporates an automatic arc-length control procedure.

Non-linear analysis of composite structures with integrated piezoelectric sensors and actuators

This paper deals with the geometrically non linear analysis of thin plate/shell laminated structures with embedded integrated piezoelectric actuors or sensors layers and/or patches.The model is based on the Kirchhoff classical laminated theory and can be applied to plate and shell adaptive structures with arbitrary shape, general mechanical and electrical loadings. the finite element model is a nonconforming single layer triangular plate/shell element with 18 degrees of fredom for the generalized displacements and one eçlectrical potential degree of freedom for each piezoelectric layer or patch. An updated Lagrangian formulation associated to Newton-Raphson technique is used to solve incrementally and iteratively the equilibrium equation.The model is applied in the solution of four illustrative cases, and the results are compared and discussedwith alternative solutions when available.

A definition of literary literacy: a content analysis of literature syllabuses and interviews with Portuguese lecturers of literature

The aim of this paper is to present a definition of literary literacy in the context of majors in languages, literatures and cultures, in Portugal. A definition of literary literacy was deduced from a content analysis of primary data sources and from the theoretical underpinnings of the transactional theory of reading. The primary data sources are fourteen Portuguese and English literature syllabuses from four Portuguese universities (Lisboa, Nova, Coimbra and Porto) and twelve interviews with Portuguese university lecturers of literature. Based on the findings of a content analysis of both syllabuses and interviews, from the lecturers‘ point of view, a literary literate student doing a major in languages, literatures and cultures must, above all, be able to contextualize literary texts and their authors both historically and culturally, must be able to present an interpretation as a coherent text, and must be able to do and organize bibliographical research.
