Bending of an Elastoplastic Five-Layer Circular Plate Symmetric in Thickness

Механика машин, механизмов и материалов
The problem of bending of a five-layer circular plate symmetric in thickness by axisymmetric distributed load is considered. The central and outer layers are assumed to be load-bearing, thin, and of increased rigidity.
