Void Coalescence in Incremental Sheet Forming by dailycious1985 is a document available to read on EtoBox.

This study introduces a new void coalescence mechanism in incremental sheet forming (ISF) that enhances the formability of sheet metals by promoting voids to coalesce along the meridianal direction rather than the thickness direction. An extended Gurson-Tvergaard-Needleman (GTN) model is developed to accurately predict ductile fracture behavior during ISF, validated through experiments on materials AA2024 and AA6061. The findings reveal that the improved plasticity in ISF is due to the formation of closely-
