Abstract
The development of a formulation of the Boundary Element Method (BEM) for application to elastic-viscoplastic analysis of plate bending is presented in this work. Reissner's theory is used, valid for thin and thick plates. Initially, Reissner's plate bending theory is presented, including the consideration of physical nonlinearity, and then, integral equations applied to Reissner's plates are shown. The theory for considering viscoplasticity is presented, as well as the procedures for its use with the BEM. In order to solve the equations that govern the problem, an incremental procedure is used and von Mises’ and Tresca's yield criteria are considered. This process offers an alternative method of solution for elasto-plastic problems, when steady-state condition is reached. Numerical examples are presented and results are compared with available solutions.
