小周期孔洞区域上弹性问题多尺度有限元计算

摘要

讨论了小周期孔洞结构弹性问题的多尺度有限元计算方法.首先,对该区域上的弹性位移问题给出了多尺度渐近展开,紧接着讨论了相应的多尺度有限元计算方法,最后给出的数值算例验证了该方法的可行性.%In this paper,the multi-scale computational method of elastic problem for the perforated structure of composite materials with small periodic configuration is presented.The two.scale asymp- totic(TSA)expression of displacement for composite materials with small periodic configuration is briefly shown at first,then the multi-scale finite element algorithm based on TSA is discussed.Finallv the numerical results evaluated by multi-scale computational method are shown.
