摘要：

The application of a generalized finite-element method to the static and dynamic analysis of plate and shell structures is presented. The displacement formulation of the finite-element method is used. A particular form of generalized variational principle is used which admits completely arbitrary displacement functions for an element. The form of the matrix equations is presented. The method of solution and the problem of dependent algebraic equations are discussed. Numerical results for a variety of polynomial displacement forms and continuity requirements are given and discussed. Limitations of the method are pointed out.
