标准范围

本文件规定了在环境温度下构建成形极限曲线(FLC)和使用线性应变路径时使用的试验条件。考虑的材料是扁平的金属材料,厚度在0.3 mm和4 mm之间。注:建议将厚度限制在4 mm以内,以使冲头直径比达到最大允许厚度。

This document specifies testing conditions for use when constructing a forming-limit curve (FLC) at ambient temperature and using linear strain paths. The material considered is flat, metallic and of thickness between 0,3 mm and 4 mm.NOTE The limitation in thickness of up to 4 mm is proposed, giving a maximum allowable thickness to the punch diameter ratio.
