چکیده:

There are many practical engineering problems which may be considered as boundary value problems (BVP). A typical BVP is governed by one or more ‘differential’ or ‘integral’ equation(s) within a specified domain, together with some conditions over the boundary of the domain. There are some situations where an analytical or a closed-form solution could be found for a given BVP, otherwise there might be no other choice but to employ an approximate procedure for the solution of the given BVP. The objective of this paper is to analysis thick plate including shear deformation through Trefftz boundary method. To achieve for this purpose, the Galerkin formulation is selected based on Hochard and Proslier presentation in 1992. In this paper, the indirect Trefftz method is discussed and the results show that the present methods are effective for both thin and thick plates. This article is organized as follows. In section 2, the basic equations based on the Reissner’s plate theory are explained in detail. Then, in section 3, the complete solutions and complete sets are presented. In section 4, the Galerkin Method is introduced into the indirect Trefftz method and in section 5, some numerical examples are shown to illustrate the efficiency of the Trefftz method. Finally, in section 6, the conclusions are drawn, briefly
