Abstract : A discussion of what is called the anisoparametric finite element method, suited for penalty constraint formulations, is presented in the context of displacement flexure elements. Two auxiliary criteria for the kinematic field are elaborated, on which basis the desired interpolation assumptions are established. Much attention is devoted to the lowest order triangular plate element. Several numerical experiments are conducted to ascertain the element performance. (Author)
