Springback Effect Prediction in Wipe Bending Process of Sheet Metal: a Ga-ann Approach
Sheet metal is one of the most important semi-finished products used in automobiles, domestic appliances, aircraft and other familiar products. Therefore sheet metal forming technology is an important engineering discipline in the area of mechanical engineering. In sheet metal forming, wipe bending process plays a major role in which the sheet metal tries to return to its original shape after r...
متن کاملAnalytical prediction of springback based on residual differential strain during sheet metal bending
As the springback of sheet metal during unloadingmay cause deviation from a desired shape, accurately predicting springback is essential for the design of sheet stamping operations. Finite-element models have not been successful in predicting springback; hence there is a need for analytical models to make such predictions. In this study, a model based on differential strains after relief from t...
متن کاملAn Alternate Method to Springback Compensation for Sheet Metal Forming
The aim of this work is to improve the accuracy of cold stamping product by accommodating springback. This is a numerical approach to improve the accuracy of springback analysis and die compensation process combining the displacement adjustment (DA) method and the spring forward (SF) algorithm. This alternate hybrid method (HM) is conducted by firstly employing DA method followed by the SF meth...
متن کاملRobust optimization strategies for sheet metal springback compensation
Sheet metal forming is a major industrial process, mainly due to its cost efficiency after the establishment of the process design. However, the process design from tools geometry to load conditions is not straightforward, as a consequence of the side effects associated with sheet metal forming. The emphasis in this area goes to the springback effect or elastic recovery, which is one of the mai...
متن کاملAn Experimental Study of Springback of Bent Sheet Metal Parts
Bending is the uniform straining of material around a straight axis and is used commonly in various sheet metal industrial products. Since all materials have a finite modulus of elasticity, plastic deformation is followed by some elastic recovery when the load is removed. In bending processes this phenomenon is called springback. Springback occurs not only in flat sheets or plate, but also in b...
