摘要
主要研究了由线弹性加强体和线粘弹性基体组成的多层复合材料,在已有的线弹性多层材料的渐过均匀化方 法的基础上,应用弹性-粘弹性对应原理,通过Burgers模型表示线粘弹性基体材料,反演得到了多层材料的有效松弛模 量和有效泊松比在时间域中的表达式。
In this paper the problem of multilayered media is studied. The matrix is assumed linear and isotropic vis-coelastic and the reinforcement is linear and isotropic elastic. Based on the asymptotic homogenization of linear elastic multilayered media, the correspondence principle in viscuelasticity is applied and the problem in the Carson domain is solved. The inversion to the lime domain of the effective relaxation moduli and the effective Poisson coefficients of multi-layered media are carried out when the Burgers model is used to represent the viscoelastic behavior of the matrix. Finally, comparisons of the experimental results and other results are presented.
