A Co continuous four-noded cylindrical shell element

摘要

A Co continuous four-noded cylindrical shell element with independent interpolations for in-plane displacements u and v; transverse displacement w and face rotations theta-x and theta-y are made efficient by using substitute smoothed shape functions for w in membrane strain evaluation. This removes 'membrane locking', making it the simplest efficient quadrilateral cylindrical shell element available. 13; 13;
