Proc. ASME. PVP2023, Volume 2: Computer Technology & Bolted Joints; Design & Analysis, V002T02A005, July 16–21, 2023
Publisher: American Society of Mechanical Engineers
Paper No: PVP2023-102278
... Abstract The application of macroscopic damage models is often made difficult by the fact that the calibration of the model parameters is associated with great experimental effort. Therefore, a methodological, simulative approach is presented to determine the damage model parameters...

Proc. ASME. PVP2021, Volume 2: Computer Technology and Bolted Joints; Design and Analysis, V002T03A048, July 13–15, 2021
Publisher: American Society of Mechanical Engineers
Paper No: PVP2021-62017
... Abstract This paper presents a numerical study on pipes ductile fracture mechanical response using a phenomenological computational damage model. The damage is controlled by an initiation criterion dependent on the stress triaxiality and the Lode angle parameter, and a post-initiation damage...

... the crack growth behavior by taking into account the misalignment of the weld and combined loads. The damage model is based on a failure surface and post-initiation behavior to model the ductile crack initiation and propagation steps, respectively. The models provide useful information to track...

Publisher: American Society of Mechanical Engineers
Paper No: PVP2019-93098
... Abstract The aim of this study is to propose the damage model on the basis of the mechanism for ductile fracture related to void growth and applicable to ductile fracture assessment for steels. In order to determine damage evolution law, void growth behavior in the material was investigated...
