This paper presents a Mindlin plate finite element for the analysis of plastic limit loads with von Mises yielding criterion. The element is derived from a natural approach, based on a mixed b-bar strain formulation. The proposed element is locking free and is able to produce accurate results for thick plates as well as for thin plates (below Kirchhoff limit). Moreover, the model also reveals a satisfactory behavior to mesh distortion sensitivity. The effectiveness of the approach is illustrated by means of some numerical examples.

Abstract

This paper presents a Mindlin plate finite element for the analysis of plastic limit loads with von Mises yielding criterion. The element is derived from a natural approach, based on a mixed b-bar strain formulation. The proposed element is locking free and is able to produce accurate results for thick plates as well as for thin plates (below Kirchhoff limit). Moreover, the model also reveals a satisfactory behavior to mesh distortion sensitivity. The effectiveness of the approach is illustrated by means of some numerical examples.
