The characterization of toughness properties in standard Charpy or fracture mechanics tests calls for thickness requirements to be met. Therefore, the characterization of toughness properties is a problem for thin‐walled structures. Replacing Charpy impact toughness testing by impact notch tensile testing can solve this problem. However, the toughness requirements are still expressed in terms of standard...
Seit mehr als zehn Jahren ist der Aufschweißbiegeversuch (AUBI) für eine Reihe von Fällen, insbesondere für Feinkornbaustähle, nicht mehr verpflichtend. Die hierzu durchgeführten Untersuchungen hatten allerdings nur eine empirisch begründete Korrelation mit der Kerbschlagarbeit hervorgebracht. So fehlt nach wie vor eine Klärung der werkstoffmechanischen Zusammenhänge, denen nachzugehen es die Aufgabe...
Sandia National Laboratories have carried out the Sandia Fracture Challenge in order to evaluate ductile damage mechanics models under conditions which are similar to those in the industrial practice. In this challenge, the prediction of load-deformation behavior and crack path of a sample that is designed for the competition under two loading rates is required with given data: the material Ti–6Al–4V,...
