Analysis benchmarking is used to evaluate new algorithms for automated VCCT-based delamination growth analysis. First, existing benchmark cases based on the Single Leg Bending (SLB) specimen for crack propagation prediction under quasi-static loading are summarized. Second, the development of new SLB-based benchmark cases to assess the static and fatigue growth prediction capabilities under mixed-mode I/II conditions is discussed in detail. Additionally, a scheme is proposed to interpolate between known fatigue delamination growth rates to obtain values for mixed-mode ratios for which data has not been defined in the input. Further, a comparison is presented, in which the benchmark cases are used to assess new analysis tools in ABAQUS/Standard FD03. These recently implemented tools yield results that are in good agreement with the benchmark examples. The ability to assess the implementation of new methods in one finite element code illustrates the value of establishing benchmark solutions.

基于疲劳载荷下单腿弯曲试样的分层增长预测的基准示例

分析基准测试用于评估基于VCCT的自动分层增长分析的新算法。首先，总结了基于单腿弯曲（SLB）标本的准静态载荷下裂纹扩展预测的现有基准案例。其次，详细讨论了基于SLB的新基准案例的开发，以评估混合模式I / II条件下的静态和疲劳增长预测能力。此外，提出了一种在已知的疲劳分层增长率之间进行插值的方案，以获取尚未在输入中定义数据的混合模式比率的值。此外，提出了一个比较，其中使用基准案例评估ABAQUS / FD03标准中的新分析工具。这些最近实施的工具产生的结果与基准示例完全一致。评估一个有限元代码中新方法的实现的能力说明了建立基准解决方案的价值。
