Zusammenfassung:	Based on the Hu-Washizu variational principle and the concept of degenerated solid shell elements, a quasi-conforming or hybrid/mixed nine-node degenerated shell finite element csh9 has been developed. This finite element is completely free from shear and membrane locking phenomena, and spurious kinematic modes are globally suppressed. Numerical tests indicate that the finite element is highly accurate and effective.
