摘要 用均匀化方法求出了周期复合材料的等效热弹性系数,得到了复合材料瞬态耦合热弹性问题对应的均匀化问题,通过计算分析了材料体分比与等效系数间的定量关系;用发展方程有限元方法求出了均匀化问题的数值解。 All of the homogenization parameters of the fully coupled dynamic thermo-elastic behavior for periodic composites are defined by using the asymptotic homogenization method.And the homogenization coupled system is also obtained.The homogenization procedure and numerical computation of effective parameters on bounded domain are given.
