A mechanism for describing 3-D local geometries is presented which is suitable for input into a classifier generator. The objective is to predict the springback that will occur when Asymmetric Incremental Sheet Forming (AISF) is applied to sheet metal to produce a desired shape so that corrective measures can be applied. The springback is localised hence the desired before shape and the actual ...

shape error due to elastic recovery of formed part in unloading known as springback, is one of the most important problems of tool design in sheet metal forming processes. many researches have been performed for proposing an efficient method to decrease or compensate springback error in sheet forming processes. these methods are usually based on iterative finite element algorithms. in this pape...

Springback prediction is one of the most challenging in finite element analysis for sheet metal forming processes. The demand requests development a kinematic hardening model and parameter identification. This study presents schematic strategy to identify parameters Chaboche’s based on differential evolution optimization method. To this goal, several tension-compression (TC) tests were conducte...

Cold drawing process is one of the most used metals forming processes in industries for forming seamless tubes. This process of plastic deformation of metals occurs below the recrystallization temperature and is generally performed at room temperature. When metal is cold worked, upon the release of forming force, the springback occurs. In this paper, the springback effect of the seamless tube t...
