Under the simple linear deteriorating, nonnegative start and stop lag deteriorating rates are introduced so as to combine jobs and construct composite jobs satisfying precedence relations.
在作业加工时间简单线性恶化下，提出作业的非负开始和停止延迟恶化率，构造了满足约束条件的复合作业。

In this paper, a modified VCCT (Virtual Crack Close Technology) is developed to compute strain energy release rates of tire belt (a kind of composite structure) under different delamination lengths.
Different tensile rates were adopted during the experiment, and the influence of loading rate on the mechanical properties of the composite material was analyzed thoroughly.
