Deployment of Smart Simulation Apps in Support of DaDT Activities
This presentation highlights a DaDT Sim App developed in support of the AFRL-SBIR Phase III project “Deep Residual Stress Method Demo Program”. The Crack Propagation Analysis Tool (CPAT) incorporates the beneficial effects of residual stresses due to cold-expansion in the computation of crack propagation life of components with cold-worked holes.

“We have been having very good success using the P-Version finite element code, StressCheck®, to develop the 2-D solutions for two independent cracks in a plate. I have asked one of our AFGROW team members to model the plate and lug cases using StressCheck® and compare them to the existing AFGROW closed-form solutions. [He] modeled the cases several different ways to be sure that he was getting the best possible solutions. He has verified that the bearing load option in StressCheck® provides excellent results”
