【摘要】 用三维各向异性有限元程序求解多层层合板层间应力是与复合材料层合结构的强度紧密相关的。利用结构的整体与局部的概念,对重点研究的区域作为局部区域按每一层不同的材料铺层划分单元。在远离求解区域的地方,用“等效模量”的概念将不同的材料层用等效的方法进行单元网格划分,这样就克服了层合板层数过多而引起的计算量太大的问题。更多还原

【Abstract】 In this paper, interlaminar stresses in laminated plateis solved by using of the three dimensional anisotropic finite elementprogram. A simplified method for calculating local interlaminarstresses is applied by smearing more laminas far away in solving lami-nation as a quasi-homogeneous lamina. Numerical example showedthat the smearing technology is very useful in engineering applica-tion.更多还原
