Numerical Investigation on Sheet Shearing Process of an Elastoplastic Metal Material with Damage Model

The sheet shearing process is a rising manufacturing technology that has attracted particular attention in industrial engineering like aerospace and automotive. However, a continuous monitoring of process parameters is always necessary to ensure both of the tooling life and the product perfection. This study has led some light in the area of FEA of metallic sheet shearing to avoid locking problem with minimizing experimentation costs. The current work is carried out to develop an-efficient non-associated plastic model integrated with isotropic ductile damage approach in order to improve the numerical procedure efficiency for sheet blanking process. For this purpose, an axisymmetric model is adapted to simulate this process via ABAQUS software code for a lower computational cost. Moreover, the developed model is implemented using user interface material subroutine (VUMAT). The main contribution of this study is to predict the influence of some relevant process parameters such as friction coefficient and punch-die clearance on part quality and to evaluate the capability of the 5083 aluminum metal at shearing deformation.
