The accurate prediction of part deformation due to solidification in automotive formed parts is important to help achieve an efficient production. Forming processes are those where a molten preform is deformed to take the shape of a mould cavity and subsequently solidified. Tolerance issues are critical in automotive applications and therefore part deformation due to solidification needs to be controlled and optimized accordingly. Formed parts can have a wide range of deformations according to the conditions of solidification.Both a small displacement and a large displacement formulation are developed for prediction of part deformation due to solidification. Experimental results obtained on a simple as well as complex automotive part are compared to determine whether the small displacement theory or the more complex approach is more appropriate.
