摘要
用杂交应力元研究复合材料展板应力问题,尤其是层间应力分布规律,获得了若干有益的结论,数值算例表明,单元在层板分析中具有很高的精度.
The stresses of composites laminates, especially the interlaminar stress, are studiedby means of the stress hybrid element. Some important conclusions are drawn. Numerical re-sults show that the stress hybrid element is of high precision in the analysis of composite lami-nates.
