Abstract: This paper presents experimental results of simple compression of a soft rubber sphere in a very large range of forces attaining at 5000 N, presenting calculational results by a set of five ...

Abstract: Deformation behavior of laminated sheet metals is estimated by the upper bound method based on Hill’s plasticity theory for anisotropic materials. The r-value and the stress-strain curve are ...

Abstract: Strength and deformation of two-phase materials are investigated by the upper bound approach in relation to the volume fraction of the second-phase particles, yield strength ratio and bond ...

Abstract: On the basis of an upper-bound approach, deformation behavior of porous metals is considered. A model for porous metals is employed to describe a kinematically admissible velocity field for ...
