| Abstract | An improved version of the Element-free Galerkin Method (EFGM) based on the Moving Kriging (MK) interpolation is presented for addressing the problems of shear locking in Mindlin plates at the small thickness limit. In this study, the presence of shear locking can be completely eliminated if the rotation fields are constructed to match the fields of slope, given by the first derivative of the displacement. By this criterion, the second derivative of the shape functions must be evaluated thus requiring at least a C1 continuity of shape functions for displacement field. Numerical results show that the modified version of EFGM with MK interpolation does not exhibit shear locking. Furthermore, the study also finds the accuracy of EFGM to be greatly enhanced with the use of MK shape functions. |
