Finite Element Analysis Considering Material Porosity 2011-36-0136

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.
