Study advances in the elastoplastic large deformation solid shell element models

A new kind of shell elements which takes account of stress and strain in the thickness direction of solid shell elements, including their concept and related theoretical basis,is introduced.The methods used in overcoming locking problems in constructing the element models are emphatically described.A numerical example is presented and the prospect of the element models this kind of element models is illustrated.
