【摘要】 本文将一空间等参拟协调元推广到复合材料层合结构的分析中,该单元既可作为块元又可视为层合板元,且特别适用于变厚度的复合材料层合结构的分析.数值实例计算表明,该单元用于薄层合板时无剪切自锁现象,有良好的计算精度和效率.更多还原

【Abstract】 In this paper a spatial iso-parametric pseudo-compatible elementis generalized to be used for the analysis of the laminated structures of com-posite material.This element can be used either as a block element or as anelement of composite plate,and it is especially suitable for the analysis oflaminated structures of composite material in the case of variable thickness.Numerical results of examples show that this element,when applied to thinlaminates,does not suffer form the phenomenon of self-locking and has prettygood precision and efficiency.更多还原
