【 摘 要 】

There are certain cases where FEM gives erroneous results due to the problem of locking. Locking phenomenon has been classified into three basic categories. shear, volumetric and membrane locking. This project discusses the causes, effects and remedies for shear locking in conventional FEM using lower order elements for bending dominated problems. New quadrature rule is considered in this project which will overcome the hour glassing effect that arises in Gauss one-point integration while solving the bending dominated problem.
