Influence of an Accurate Trimming operation on Springback
When a sheet metal forming operation, such as deep drawing, is followed by a trimming operation the numerical springback is influenced by various physical parameters and numerical factors. Two techniques of taking into the account the stress state change due to cutting in the FE plate model are discussed in the present paper. The first technique concentrates on the effect of the element mesh cu...
متن کاملNumerical and Experimental Investigations on Springback of U-bending of DP600 Steel Alloy Sheet
The most prominent feature of sheet material forming process is an elastic recovery phenomenon during unloading which leads to springback and side wall curl. Therefore evaluation of springback and side wall curl is mandatory for production of precise products. In this paper, the effects of some parameters such as friction coefficient, sheet thickness, yield strength of sheet and blank-holder fo...
متن کاملSpringback Modeling in L-bending Process Using Continuum Damage Mechanics Concept
Springback is one of the most common and important issues in metal forming area. Due to the fact that springback depends on a variety of parameters, it is hard to predict. Hence, in this paper, the effect of continuum damage mechanics (CDM) on springback was investigated based on the Lemaitre isotropic unified damage law. Swift’s hardening law was employed to describe isotropic hardening behavi...
متن کاملSpringback Analysis in Advanced High Strength Steel Using a New Flexible Semi-industrial Tool Geometry, the Flex-rail A.andersson
The automotive industry is using more and more of Advanced High Strength Steel in order to reduce the weight of the car. Since this will generate more springback, it is of vital importance to be able to predict the amount of springback in the parts. Otherwise, many late changes have to be made in order to fit the parts in their position. In order to increase the ability to understand and test t...
متن کاملNumerical Product Design: Springback Prediction, Compensation and Optimization
Numerical simulations are being deployed widely for product design. However, the accuracy of the numerical tools is not yet always sufficiently accurate and reliable. This article focuses on the current state and recent developments in different stages of product design: springback prediction, springback compensation and optimization by Finite Element (FE) Analysis. To improve the springback pr...
