## Abstract A mixed variational principle is developed and utilized in a finite element formulation. The procedure is mixed in the sense that it is based upon a combination of modified potential and complementary energy principles. Compatibility and equilibrium are satisfied throughout the domain _

New variational principles with relaxed interelement continuity requirement are developed for geometrically non-linear analysis, and the reยฎned non-conforming element methods are given. A simple modiยฎcation of the constant strain can be introduced into the formulation, and the remaining procedures a
