Název v původním jazyce

Determination of mechanical properties of materials with complex inner structure using microstructural models

Popis výsledku v původním jazyce

In this paper, mechanical behavior of cellular materials is studied by modeling their internal structure and analysis using Finite Element Method (FEM). Alporas aluminium foam was selected as a reference material and the material characteristics were derived from tensile loading using numerical FEM analysis. Internal structure of the foam was modeled by two different methods - using voxel model created on the basis of a series of CT scans and by discretization using Gibson-Ashby's cellular model. Mechanical behavior analysis was performed in both elastic and plastic fields. The beam-only discretization is considered intentionally to investigate its suitability for modeling of closed cell foams and trabecular bone.
