|Issue Date:||Dec-1996||Citation:||Swaddiwudhipong, S., Liu, Z.S. (1996-12). Dynamic response of large strain elasto-plastic plate and shell structures. Thin-Walled Structures 26 (4) : 223-239. ScholarBank@NUS Repository. https://doi.org/10.1016/0263-8231(96)00031-6||Abstract:||Large strain, elasto-plastic response of plate and shell structures have been carried out. A nine-node degenerated shell element with assumed strain fields is modified to take into account the effect of large strain, large displacement as well as the change in shell thickness during the deformation process. An Updated Lagrangian approach is adopted in the formulation of the incremental form of the governing equations. A time marching scheme is carried out based on Newmark's time integration technique. The results from the present study as compared with existing experimental, analytical as well as other finite element solutions agree reasonably well. Convergence studies indicate that the proposed elements give results which converge rapidly to acceptable solutions.
