开发了制造过程模拟软件（DEFORM）和概率损伤容限分析软件（达尔文）之间的接口，用于计算体残余应力和平均晶粒尺寸。这些接口允许制造过程模拟的全场结果被纳入断裂寿命和可靠性的预测。提出了局部残余应力和平均晶粒尺寸对裂纹扩展行为影响的模拟方法。该接口和所提出的方法在原型软件中实现，并用于理想化发动机盘的演示示例。该练习展示了集成计算材料工程（ICME）直接解决组件完整性的实际潜力。
Interfaces between manufacturing process simulation software (DEFORM) and probabilistic damage tolerance analysis software (DARWIN) have been developed for bulk residual stresses and average grain size. These interfaces permit full-field results from manufacturing process simulations to be incorporated in predictions of fracture life and reliability. Approaches were presented for modeling the effects of location-specific bulk residual stress and average grain size on crack growth behavior. The interface and the proposed approaches were implemented in prototype software and used to perform demonstration examples for an idealized engine disk. The exercise demonstrates the practical potential for Integrated Computational Materials Engineering (ICME) that directly addresses component integrity.
