Crack Propagation Analysis Tool for 3D Crack Simulation: A Simulation App Case Study
Abstract: This 2 hour course will provide instructions for using the Crack Propagation Analysis Tool (CPAT) to simulate 3D crack growth at a fastener hole in a fatigue test specimen. Residual stresses due to cold-working of the hole are taken into account. CPAT provides an easy-to-use interface which significantly reduces the manual effort involved in complex crack growth simulations using the finite element method. Finite element solutions are computed using the StressCheck solver, renowned in the aerospace finite element analysis community for extracting high quality stress intensity factors (SIFs) for complex parts and assemblies.
Originally presented as a training course at the 2017 ASIP conference in Jacksonville, FL.

“Of the three FEA products we use, StressCheck® gives me the most confidence when it comes to performing post-processing quality checks on multi-body contact analysis results. StressCheck® has the capability to extract any data of interest and convergence information for that data at any location in the model domain; the other two FEA products do not. And when it comes to interference fit multi-body contact solutions, I haven’t found any software to outperform StressCheck®.”
