This study investigates the effect of the forming angle on the deformation behavior of copper sheets subjected to Single Point Incremental Forming (SPIF). The distribution of plastic equivalent strain (PEEQ) and Von Mises stress during the formation of truncated cones was analyzed using the Finite Element Analysis (FEA) method implemented in ABAQUS software. The findings demonstrate that the forming angle has a significant impact on the magnitude of deformation and stress concentration at the cone apex, with Von Mises stresses, in certain cases, exceeding the material’s yield strength. This research offers a framework for informed selection of forming angles, process optimization within SPIF, and enhancement of final product quality.

摘要

This study investigates the effect of the forming angle on the deformation behavior of copper sheets subjected to Single Point Incremental Forming (SPIF).

The findings demonstrate that the forming angle has a significant impact on the magnitude of deformation and stress concentration at the cone apex, with Von Mises stresses, in certain cases, exceeding the material’s yield strength.
