| Abstract | Dynamic analyses by the finite element methods (FEM) with kriging shape function (kriging-based finite element methods) are presented in this study. Previous study has shown that application of kriging-based FEM shows remarkable accuracy for elastostatic problem (Plengkhom and Kanok-Nukulchai, 2005). In this study, the application of kriging-based FEM is enhanced to dynamic problems. One dimensional (Timoshenko beam) and two dimensional (Plane stress and Mindlin plate) dynamic analyses are conducted. Some numerical examples of free and forced vibration are taken to evaluate the accuracy of the method. For each analysis, the accuracy of kriging-based FEM is compared with the standard FEM. The result shows that for one dimensional problem, kriging-based FEM are only slightly more accurate than standard FEM, but for two dimensional problems kriging-based FEM shows significant improvement of accuracy compared with the standard FEM. It is found also that additional layer for domain of influence will improve the accuracy of Kriging-based FEM |
