RISChallenges in Validation of Computational Weld Mechanics Code to Compute Residual Stress and Distortion in Welds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Validation of a computational weld mechanics (CWM) code for a particular welding application requires an estimate of the difference between experimentally measured parameters and parameters computed by a computational ...
An Integrated Computational Welding Mechanics With Direct Search Optimization for Mitigation of Distortion in an Aluminum Bar Using Side Heating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Using a computational weld mechanics (CWM) framework for exploring a design space, a recent directsearch algorithm from Kolda, Lewis and Torczon is modified to use a leastsquare approximation to improve the method of ...
Optimizing Temper Bead Welding by Computational Weld Mechanics and Design of Experiment Matrix
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Temper bead welding is usually done by experiment, i.e., trial and error. This paper describes a computational weld mechanics model to compute the transient temperature and transient microstructure evolution in temper bead ...
