| Abstract: | Heferosis degenerated three-dimensional bending shell element suited to the laminated thin and thick plates and shells are used to analyze etastic and plastic of metal matrix composite laminated plates and shells with Hill yield criterion and layered model method. Calculated results of examples show that the method is reltable with higher precision. |
