摘要
提出了一种适合于双模量复合材料层合板静动力分析的高阶理论有限元分析方法。采用四结点２８自由度的矩形板单元，建立了有限元方程，最后给出了算例。计算结果表明，其有限元解与解析解吻合很好。
This paper has offered a higher order finite element theory for static and dynamic analysis of double modulus laminated composite plate. The finite element equation is established by making use of rectangular plate element with 4 joints and 28 freedoms, compared with the calculation results,it is coincident with both solutions for analysis and finite element.
