Finite Element Analysis Considering Material Porosity

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.
