RISDynamic Recrystallization in Laser Impact Welding Driven by Surface Morphology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Laser impact welding (LIW) is a high-speed, small-scale, solid-state metal joining process in which a thin flyer collides with a target, producing localized severe deformation and heating that could activate ...
An Efficient Multi-Scale Modeling Method that Reveals Coupled Effects Between Surface Roughness and Roll-Stack Deformation in Cold Sheet Rolling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In thin-gauge cold rolling of metal sheet, the surface roughness of work rolls (WRs) is known to affect the rolled sheet surface morphology, the required rolling load, and the roll wear. While modeling of rough surfaces ...
Probabilistic Force Prediction in Cold Sheet Rolling by Bayesian Inference
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A primary factor in manufacturing highquality coldrolled sheet is the ability to accurately predict the required rolling force. Rolling force directly influences rollstack deflections, which correlate to strip thickness ...
An Efficient Reliability-Based Simulation Method for Optimum Laser Peening Treatment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method is introduced for efficient reliability-based design of laser peening (LP) surface treatment to extend fatigue life of metal components. The method includes nonparametric probability density estimation, surrogate ...
