Press 1 (Analysis) Small Exhibition Hall 2nd Floor 403 - High-Precision Sheet Metal Forming Analysis Using a Moving Hardening Material Model Considering SD Effects In line with the trend of vehicle lightweighting, the use of aluminum and high-strength steel sheets is increasing. Forming analysis for evaluating the formability of such sheets is actively conducted, utilizing various material models. This research developed a material model that considers the Strength Differential Effect (SD Effect) and moving hardening, and introduced the developed material model into the AutoForm R&D Plugin. The existing material models and the developed model were incorporated into the forming analysis, and the results were compared and evaluated.
