Anisotropic thin plate bending problems by Trefftz boundary collocation method

Trefftz boundary collocation method is used to analyse the bending of anisotropic thin plates. Compared with the existing collocation methods employing complicated fundamental solutions in which the source points are located outside the plate, boundary collocation method presented in this article is relatively simple. It requires only the general solution of anisotropic thin plate bending problems and no singular integrals appear in the formulation. The collocation points are located along the plate edges. The implementation of the related computer codes is fairly straightforward. Numerical results are generally more accurate compared with existing solutions.
