Elastic, Plastic Bending of a Built-in Circular Plate Under a Uniformly Distributed Load

摘要

The paper contains an analysis of the bending moments and deflections of a uniformly loaded and built-in circular plate that is made of an incompressible elastic, plastic material obeying Tresca's yield condition and the associated flow rule. The analysis is simplified by assuming that any plate element is either entirely elastic or entirely plastic. This assumption is practically fulfilled for a sandwich plate: for a solid plate it represents a first approximation to the actual diagram of bending moment versus curvature.
