This document provides a review of soft computing techniques that have been applied in materials engineering, with a focus on sheet metals. It discusses that soft computing methods like artificial neural networks, genetic algorithms, and other evolutionary algorithms have shown promising results when applied to problems in materials design, modeling properties, process optimization and control. The document reviews several studies that have used these techniques for materials proportion prediction, properties modeling, optimization and other applications. However, it also notes that the interface between materials engineering and intelligent systems techniques is still unclear and more work needs to be done to formalize the methodology.
