Hybrid stress-based finite elements with side displacement fields have been used to generate equilibrium models having the property of equilibrium in a strong form. This paper establishes the static and kinematic characteristics of a flat triangular hybrid equilibrium element with both membrane and

## Abstract A rankβsufficient flat triangular shell element with drilling degreesβofβfreedom is described. A variational basis for this element has been provided by a threeβfield variational principle with relaxed interelement compatibility and traction continuity conditions. A generalized spurious
A quadrilateral membrane finite element with drilling degrees of freedom is derived from variational principles employing an independent rotation field. Both displacement based and mixed approaches are investigated. The element exhibits excellent accuracy characteristics. When combined with a plate
