An Integrated computational and experimental methodology for stochastic prediction of elastic-plastic fracture parameters and probabilistic characterization of fracture initiation and loads for two-and three-dimensional cracked structures is developed. The developments have a broad impact on standard industry practices of equipment reliability, remaining life assessment, and fracture control. The developments are also integrated into the training of undergraduate and graduate students. A textbook incorporating these advances is prepared.

本文发展了一种综合计算和实验方法，用于二维和三维裂纹结构的弹塑性断裂参数的随机预测和断裂起始和载荷的概率表征。这些发展对设备可靠性、剩余寿命评估和断裂控制的标准行业实践产生了广泛的影响。这些发展也纳入了本科生和研究生的培训。编写了一本纳入这些进展的教科书。
