The Influence of Process Parameters on Single Point Incremental Forming: Numerical Investigation
- 69 Downloads
In this paper, elasto-plastic model based on non-associated flow rule is implemented in Abaqus/Explicit software via VUMAT subroutine to study the influence of some process parameters: cone wall angle, tool diameter, and sheet thickness, on the formability, plastic deformation and thinning during single point incremental forming (SPIF) process. The present work presents useful guidance to show the effect of these three parameters in improving the quality of manufactured products and in obtaining a better formability during SPIF process.
