Dynamic large deflection analysis of elastic-plastic beams and plates

An investigation of large deflections of elastic-plastic beams and plates are investigated by the pseudo-normal mode superposition method is presented. The geometrical nonlinear versions of the Mindlin plate theory and the Timoshenko beam theory was used in the analysis. The results obtained numerically for the responses of beams and circular plates were compared with published experimental and numerical results as well as with existing analytical solutions.
