Abstract:
Quasi-static and impact compressions of a body of spherical contact zone and a rigid plane were analyzed. Modified upper and lower bound theorems of plasticity were used in order to include dynamic effects. Velocity field of the plastic flow and propagation of the failure zone were simulated. Numerical examples for bruising of apples during quasi-static and impact loadings were calculated. Strain rate dependence of the failure stress was obtained from experimental data and utilized for the computation. Numerical values calculated by the upper and lower bound models bounded the experimental results from above and below. Further development of the upper bound model brought the calculated results closer to the experimental ones. These models help to gain insight into the actual mechanism of the failure process and the plastic-flow in spherical bodies during collision.
