Abstract:Thermal bending problem of thin plate is analyzed by the hybrid boundary node method in this paper. The boundary local integral equation of isotropic thin plate is established based on thermal elastic theory and modified variational principle of thin plate. The domain variables are interpolated by fundamental solution, while the boundary variables are approximated by moving least squares. Only discrete nodes are constructed on the boundary, and no meshes are needed either for the purpose of interpolation of the solution variables, or for the numerical integration, so the present method is a truly boundary type meshless method. The numerical examples show that this approach has such advantages as high efficiency, good accuracy and high convergence rate.
