SUMMARY:Determination of impact toughness of sheet material by using impact tensile test
DESCRIPTION:Thickness requirements must be met when determining toughness properties in typical Charpy or fracture mechanics testing. As a result, the characterization of toughness qualities is a challenge in thin-walled constructions. This problem can be solved by replacing Charpy impact toughness testing with impact notch tensile testing. Toughness requirements, however, are still specified in terms of conventional test findings. As a result, a framework for translating these standard test criteria into impact-notch tensile test requirements is proposed here. The proposed framework is based on numerical simulations with a phenomenological damage mechanics model, which predicts local damage and global fracture using state-of-stress-dependent, strain-based criteria. This model considers the impacts of non-proportional strain routes and uses different cleavage and ductile fracture criteria to accurately anticipate the activation of cleavage and ductile fracture mechanisms in the associated numerical simulations.
