“…The present formulation includes only two additional degrees of freedom to conserve computational efficiency along with improved accuracy. The geometric nonlinear damped circular plate analysis has been dealt in [23]. The material nonlinear dynamic analysis of the plate with special emphasis on damping is not investigated till date to the best of authors' knowledge and this paper aims at bridging this gap.…”

Damped transient dynamic elasto-plastic analysis of plate is investigated. A finite element model based on a C 0 higher order shear deformation theory has been developed. Nine noded Lagrangian elements with five degrees of freedom per node are used. Selective Gauss integration is used to evaluate energy terms so as to avoid shear locking and spurious mechanisms. Von Mises and Tresca yield criteria are incorporated along with associated flow rules. Explicit central difference time stepping scheme is employed to integrate temporal equations. The mass matrix is diagonalized by using the efficient proportional mass lumping scheme. A program is developed for damped transient dynamic finite element analysis of elasto-plastic plate.Several numerical examples are studied to unfold different facets of damping of elasto-plastic plates.
