Abstract
Understanding macroscale ductile failure is of importance for the design of macroscale components for today’s use. Ductile failure has been investigated for decades and a multitude of simulation tools exist. However, the comparison and evaluation of the applicability of these tools is limited. This study uses an approach which separates material and fracture description into two modules. It uses uniaxial tension experiments to automatically establish the material properties for a nonlinear elastic and nonlinear plastic model. A fracture toughness sample is used to determine the failure properties. Using both modules, the behavior of a third geometry is predicted. Post-simulation experiments validate and falsify the numerical predictions. This study finds that accurate knowledge of the material is essential even in failure dominated components. The importance of shear failure mechanisms in the description of ductile failure is addressed.
