Abstract
The paper deals with a study of the significance of elastoplastic transition state in the dynamic response ofEuler beams and thin plates. The study is based on a comparative evaluation of the responses predicted by two independent approaches that use (i) stressstrain relation and basic plasticity theory and (ii) moment-curvature relation; assuming the shape factor to be unity. Responses are evaluated by way of finite-element idealization followed by numerical integration. It is found that the simplified model, based on moment- curvature relations, underestimates the response by a significant amount for longer durations of the applied load.
