摘要：
A meshless method to solve elastostatic problems based on an equilibrium model is presented. This means that the equilibrium and constitutive equations are satisfied a priori and that the approximation only concerns the compatibility equations. The application of this method together with the classical displacement meshless method leads to upper and lower bounds on the energy. The difference between these bounds gives a global error estimation on the solution. Copyright (C) 2002 John Wiley Sons, Ltd.
