A Geometry-Based Welding Distortion Prediction Tool. [PDF]

open access: yesMaterials (Basel), 2021
The prediction of welding distortion requires expertise in computer simulation programs, a clear definition of the nonlinear material properties, and mesh settings together with the nonlinear solution settings of a coupled thermal–structural analysis. The purpose of this paper is to present the validation of an automatic simulation tool implemented in ...
