Such validations show that the damage and failure model is suited for modelling of material failure and fracture evolution of specimens without damage. A thorough validation of the simulation results was conducted against results from laboratory testing. Numerical modelling of well-known fracture mechanical tests was conducted using a failure and damage model to control damage and fracture evolution. This article discusses the fracture modelling accuracy of strain-driven ductile fracture models when introducing damage of high strength sheet steel.
