DYNAMIC PLASTIC BEHAVIOR OF STRUCTURES UNDER IMPACT LOADING INVESTIGATION BY THE EXTENDED HAMILTON'S PRINCIPLE

The extended Hamilton's principle is proposed to investigate the dynamic plastic behavior of a beam or a plate under an impact loading. Material is assumed to be rigid perfectly plastic. The impact loading is given in the form of initial velocity. Good agreement between numerical solutions and experimental results done by E.W. Parks and N. Jones indicates that the proposed variational method is an efficient approximation method for the dynamic plasticity analysis. The effect of strain-rate senisitivity on the permanent deflection of a plate is investigated.
