Interfaces between manufacturing process simulation software (DEFORM TM ) 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
