Abstract
In this study, linear static analysis of continuum shell structures is conducted by using a degenerated shell element which is developed by using isogeometric approach. Notably, the present isogeomeric shell element uses the positions of control points to create the normal vector via the mapping between control points and associated points on real surface. A series of benchmark tests are performed to verify the performance of the present isogeometric degenerated shell element. From numerical test, the present shell element can overcome locking phenomena with only use of refinements and therefore any special treatment such as reduced integration, assumed strains, non-conforming modes are not required in the formulation.
