Finite Element Modeling of Shear-slitting Process

摘要

Shear-slitting is a sheet metal cutting process used for dividing coiled sheet into narrower coils. In this paper, a two-dimensional finite element model was developed for the calculation of the shear-slitting process by using ABAQUS/Explicit. The shear failure criteria and the element-delete method were adopted to model the material separation. Mass scaling was used to reduce the solution time. The effect of clearance on the burr height was investigated. The simulation results show good agreement with experimental results. The critical clearance values was suggested for decreasing the burr.
