MAGAGNIN F., N. Long Fíber Composíte Materiais Lamínated Piates : Constituem Materiais Propertíes ; Laminae Equívaients Properties ; Failure Criteria and Fínite Eiement Method Anaiysis. São Carlos, 1996. 147p. Dissertação (Mestrado) . Escola de Engenharia de São Carlos, Universidade de São Paulo. Long fiber composite materiais have been standing out among the group of new materiais in development with wide industrial application and also in civil construccion. Here is elaborated an introductory text in laminated plates field consti tuted o f long fiber composite laminae. Starting from constituent materiais properties, fiber and matrix, the theories for determination of laminae equivalent properties are presented. Elastic anisotropy theory is formulated and the bending laminated theory is developed. Conclusions about the coupling efforts in such structures are showed. Fiber, matrix and the interface between both failure basic modes are presented, as well as delamination basic modes. Some failure criteria are showed, as well as a yielding criteria. At the end some examples illustrate the finite element method analysis of such structures made by available literature programme with temperature analysis subroutine implementation.
