✦ Synopsis


An iterative correction method is proposed to enhance the otherwise poor performance of QUAD8 element in the presence of mesh distortions. The method is based on the idea of applying corrective nodal loads iteratively in order to reduce the malicious e ects of mesh distortions. The e ectiveness of the method is demonstrated for typical illustrative problems using meshes having di erent types of mesh distortions of varying degree. The mathematical condition for convergence is discussed. Copyright
