Abstract
In the present study, a finite element method was carried out on the single
point incremental forming process of explosive-welded Al/Cu bimetal. The
effect of process parameters, such as the tool diameter, vertical pitch, sheet
thickness, pyramid angle, and process strategies, were investigated on the
forming forces, dimensional accuracy, and thickness distribution of a truncated
pyramid with FEM approaches. The results obtained from the simulation
were validated by experiments. The findings indicated that by increasing
the tool radius and vertical pitch size, the forming force increases and the
wall thickness decreases. The finite element prediction for forming force,
thickness distribution, and process strategies shown good agreement with
experiments.
