ANALYSIS OF THE LARGE DEFLECTION DYNAMIC RESPONSE OF SIMPLY-SUPPORTED CIRCULAR PLATES BY THE "MEMBRANE FACTOR METHOD"

Based on the energy equilibrium, a new procedure called Membrane Factor Method is developed to analyze the dynamic plastic response of plates with deflections in the range where bending moments and membrane forces both are important. The final deflection of a simply-supported circular rigid plastic plate loaded by a uniformly distributed impulse is obtained. In comparison with other approximate solutions, the present method is found to be simplier and the results in better agreement with the corresponding e...
