灰色预测是通过鉴别系统因素之间发展趋势的相异程度，即进行关联分析，并对原始数据进行生成处理来寻找系统变动的规律。(The grey prediction is to identify the different degree of the development trend between the factors of the system, that is, to carry on the correlation analysis, and to process the original data to find the law of the system change.)

说明：  These composite materials generally exhibit brittle damage behavior. The anisotropy in the material and different kinds of failure mechanisms make it difficult to accurately characterize the behavior of composite materials. The present work aims to verify and apply the Puck Failure Criteria using the commercially available finite element package ANSYS by writing a user-material subroutine in FORTRAN. The model is implemented with different post failure degradation schemes EWM/CSE.
