## Abstract A new method for the formulation of hybrid elements by the Hellinger‐Reissner principle is established by expanding the essential terms of the assumed stresses as complete polynomials in the natural coordinates of the element. The equilibrium conditions are imposed in a variational sens

Based on Hellinger}Reissner functional and with the inclusion both of displacements and stresses, a hybrid stress formulation of dynamic "nite element method is derived in this paper. In this formulation, the displacements are separated into zeroth displacement modes and high-order incompatible dyna

The paper is concerned with the ΓΏnite element formulation of a recently proposed geometrically exact shell theory with natural inclusion of drilling degrees of freedom. Stress hybrid ΓΏnite elements are contrasted by strain hybrid elements as well as enhanced strain elements. Numerical investigations
