Abstract:For h-lype adaptive finite element method, the local mesh refinement introduces irregular nodes and destroys the standard continuity between elements. The reference nodes of the irregular are used to interpolate element coordinates and displacements.The improved shape functions, of which the conventional shape functions. are a particular case, are presented to guarantee the continuity, No changes but the shape functions are needed when the mcthod is applied in finite element programs.the computational results the features of the method.higher accuracy,simplicity.fewer degrees of freedom and less computation effort.
Keywords:adaptivc mesh finite element error estimation
