text: Computational methods have been increasing in popularity as a method to test possible root because they do not need to sacrifice a component to prove a root cause. Common cases where computational methods are used are for failures due to erosion, failures of components under complex stress states, and for predictive analyses. Computational fluid dynamics is used to determine the flow pattern and shear stresses on a component that had failed due to erosive wear. Finite element analysis is used to model components under complex stress states. Finite element analysis as well as phase field models can be used for predicting crack propagation and failure, which are then used to prevent failure by influencing component design.
