A Layerwise Dynamic Non-Linear Formulation for Multi-Layered Panels in the Presence of Viscoelastic Layer and Sma Wires, Ph.D. Dissertation Sharif University of Technology ; Hosseini Kordkheili, Ali (Supervisor)
Abstract
This thesis aims to introduce a numerical method for investigating the appropriate arrangement of visco-pseudo-elastic dampers applicable to shell and plate structures under large deformation. These passive dampers are considered as viscoelastic layers and discrete shape memory alloy (SMA) wires in which this combination improves their overall efficiency and reduces their drawbacks. Also, the main advantages of these dampers are discussed during some illustrative problems. The current finite element formulation is based on an incremental updated Lagrangian (UL) approach along with the Newmark's integration technique. In the layerwise shell element, the Mindlin-Reissner theory is adopted in...
