A compatible triangular element including vertex rotations for plane elasticity analysis. (English) Zbl 0548.73049

Summary: A remarkably simple triangular finite element for plane elasticity analysis is derived from compatible quadratic displacements with vertex connectors which include rotations. Numerical results show that quite acceptable accuracy is available for practical applications.
