Abstract

A hybrid finite element algorithm is formulated on the basis of the principles of virtual stress and displacement. This algorithm has been implemented in two types of quadrilateral planar hybrid elements with stress singular terms for the application to fracture mechanics problems. This hybid elements scheme was incorporated into an existing code, TEPSAC for the thermoelastic-plastic-creep analysis of solids[1] and comparisons of results by different elements have been made.
