Abstract:

According to a generalized variational principle, which relaxes the inter element continuity requirements, a generalized hybrid degenerated shell element was first formulated by introducing incompatible modes. Numerical examples demonstrate that the four node degenerated shell element proposed in this article has excellent performance and can avoid all kinds of locking problems.

Key words: geometrically non-linear ity, incompatible modes, gener alized hybr id degener atedshell element
