| Abstract: | A general and efficient element is discussed for elasto plastic analysis of plates and shells. This element has six degrees of freedom per node, and is obtained by combining the Mindlin plate bending element and the membrance element with driling degree of freedom. The layered model is used for elasto plastic analysis in the thickness direction. The results of numerical examples show that the present method is feasiable and reliable. |

| Keywords: | plate shell element elasto plasticity drilling degrees of freedom layered model |
