Airy Stress Function-Based Elastoplastic Analysis of Plates with Holes Using the Nonconforming Morley Finite Element Method
This paper presents a stress-function-based finite element formulation for two-dimensional elastoplastic plane-stress problems with holes. The Airy stress function is used as the primary global unknown, and the resulting non-homogeneous biharmonic equation is discretized with the nonconforming Morley finite element. Th...
