The replacement of metallic materials by polymer matrix composites which possess a multitude of improved properties (lower density, higher stiffness and strength, resistance to fatigue and damage, high temperature stability, etc) is becoming a main objective in several industries including aerospace, automotive and construction. Structural components used in such industries often include sharp radii and angles, which have proven to be difficult to form on a controlled basis because of the spring-back or spring-in phenomenon. During the forming and cooling cycles, spring-back or spring-in can cause up to 4 degrees of error on the fabricated parts and it poses more problems on thick parts. The intern in this project will be working on a (finite element) modeling, simulation, and optimization approach to predict and minimize this effect for a V]shape roll formed profile made of a typical woven composite material and used in bridge deck slabs. Once validated (by comparing to available test data as AS Composite), the model can be modified and used for similar materials and parts with different profiles.
