Análise estática de vigas compósitas laminadas de alta ordem funcionalmente graduadas e porosas : uma abordagem via MEF Espectral

Abstract

Some of the most recent developments in Materials Engineering, a field strongly associated with Civil Engineering, are new types of composite materials, such as laminate and functionally graded materials (FGMs). In these materials, the properties vary continuously through the thickness, avoiding undesired discontinuity effects in the stress fields which may cause delamination between layers. Due to the growing importance of FGMs, it’s essential to strive for better comprehension and mechanical modelling of the behavior of structures composed of these materials. In the present work, the numeric formulation via finite element method (FEM) with spectral approximations for the static analysis of high order laminated beams with porosity and FGM considerations is developed. The computational implementation is done in the programming language Fortran, and various examples from literature are tested for its validation.
