Microstructure-Sensitive Description of the Residual Stressability of Components With the Aid of Virtual Experiments

Maximilian Neite, Michael Dölz, Markus Könemann, Sebastian Münstermann
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
https://doi.org/10.1115/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...

Numerical Investigation of Ductile Fracture in Pipelines Under Complex Loading Using a Phenomenological Damage Model

Iago S. Santos, Diego F. B. Sarzosa
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
https://doi.org/10.1115/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...
