本文提出了一种应用周波法预测粘弹性行为的方法。周向理论是一种非局部连续介质理论，当它应用于弹性材料时，它显示了固有的裂纹萌生和裂纹扩展准则。该方法是为了解决传统有限元法（FEM）无法预测裂纹和失效等奇异性的问题而发展起来的。在这项工作中，周波是专门适用于粘弹性材料，以加强该方法。结果表明，周波法能较准确地预测线性粘弹性。
This paper presents an application of the peridynamic method to predict a viscoelastic behavior. The peridynamic theory is a nonlocal continuum theory that shows an inherent crack initiation and crack growth criterion when it is applied on elastic material. This method is developed in order to resolve the problem of conventional finite element method (FEM) which is unable to predict singularities such as crack and failure. In this work, peridynamic is specifically applied to viscoelastic material in order to enhance the method. It is shown in the result that peridynamic method is able to predict linear viscoelasticity with acceptable accuracy regarding to an experimental data.
