摘要
在文[1]的基础上,构造了16—20结点夹层板壳单元.该单元考虑了层合结构的横向剪切效应,较等效单层理论和分层理论的精度高,且大大减少了结点自由度数目,提高了计算效率.由于结点自由度只有线位移,该单元易与三维实体单元连接,对厚板壳也有很强的适应性,特别适合于实际工程中层合结构的计算.
Based on docement[1], the element of 16 - 20 nodes laminated Plate/shell is estabil-ished. Compared with Single - layer and laminated theory, the kind of element takes account of transverse Shear deformation, greatly reduces fredom of nodes, and upgrades efficiency of Calculation. Only being linear deformation of node fredoms,the element can be joined with 3D - element Conveniently,has powerful adaptability for thickness of plate/shell, as a result, it is an appropriate laminated element for engineering Computer.
