A slender elastic bar moving with a uniform velocity V is considered to impact a rigid half space, see Figure (3.18). The analysis is performed to calculate the generated impact stresses in the bar material.
The bar is chosen to be the contactor body and it is discretized using twenty eight-node 3 D solid elements. The contactor surface consists of one four node segment. The rigid half space is the target body and the target surface is defined by four nodes each having no degrees of freedom. The average impact stress at the bar tip is found to be 1.0 which agrees with both the analytical and numerical solution presented in .
