| Abstract: | A 20 DOF hybrid stress element based upon Mindlin plate theory is developed by using the optimization design method for thin and moderately thick shell. It is of quadrilateral shape with only four corner nodes, and can be used to shallow or deep shells with excellent performance and the "shear locking" problem is no longer existed. |
