The mechanical properties of open cell structures are investigated by Finite
Various three-dimensional generic structures built from an elastic-plastic
bulk material are treated both with regular architectures and disordered
Their elastic and elastic-plastic behavior as well as their susceptibility
to deformation localization and their defect sensitivity are analyzed.
The direction dependent responses are predicted and the governing deformation
mechanisms at cell level are identified.
