Abstract
A finite strain elasto-plastic formulation is developed for the MITC4 shell element. The developed formulation is based on Lee's multiplicat ive decomposition of the deformation gradient and on the hyperelastic expression of Von Mises flow rule expressed in terms of Hencky's strai n tenser. The formulation incorporates thickness stretching degrees of freedom that are condensed at the element level by imposing the class ical 'in-layer' plane stress condition. A symmetric and consistent tan gent stiffness matrix is also developed.
