Polygonal finite elements displaying linear displacement on specified edges and quadratic displacement elsewhere are formed. Models composed of these elements identified with simple quadrilateral meshes produce marked improvement in stress simulation with the same global degrees of freedom used in conventional models. The polygonal elements are constructed of quadratic triangular subelements with appropriate sides constrained to displace linearly. Compatible mesh refinement capability is shown.
