Abstract:

The paper proposes a hybird stress element for bending anal ysis of composite laminated plates with various thickness.The element does not display locking phenomenon of Mindlin plates when it becomes thin.Compared with the V2 element by Spilker, the present element can largely save CPU time and in-core storage while maintaining the same accuracy.

Key words: composite laminated plates, finite element analysis, hybrid- stress element
