The application of finite element method (FEM) is widespread used to structural analysis. However the prescription or the consideration of a porous material parameter is still challenging. Thus, this work proposes a methodology applied to the finite element method considering a value of porosity. The goal is evaluate the structural behavior considering prescription of material porosity for 03 (three) loading conditions: analysis of natural frequencies extraction; analysis for concentrated load; analysis for inertial loading. Also is presented a comparison between different mesh refinement (size of element), and damaged elasticity modulus.
