Experimental and numerical investigations on forming limit curves in micro forming
TLDR
The Forming limit diagram is an important tool in metal forming processes, as it indicates the failure limits for ductile damage and onsite necking as mentioned in this paper, and it can be used to estimate the failure probability of micro-thin metal sheets.Abstract:
