Abstract
Wrinkling is one of the major defects in forming processes of auto-body panels. This paper focuses on application of universal formability technology to analyze and eliminate wrinkling defect. To analyze refinedly and eliminate efficiently, universal formability technology is introduced into finite element environment. This paper presents a procedure of formability simulation analysis for wrinkles appeared on an auto fender model. The analysis results provide the approaches to eliminating wrinkles, which demonstrates the effectiveness of universal formability technology to analyze wrinkling phenomenon. The study also shows the feasibility of universal formability technology introduced into finite element environment.
