Table 1 Mechanical properties in terms of yield strength Rp02, tensile strength Rm and elongation A80, evaluated from uniaxial tensile tests of sheet metal grades used in the study

From: Strain and stress conditions at crack initiation during shearing of medium- and high-strength steel sheet

Material	Rp02	Rm	A80	h	K [MPa]	n
strength	[MPa]	[MPa]	[%]	[mm]		[—]
Medium	450	520	25	5.97–6.03	880	0.127
High	1080	1260	7	6.11–6.15	1550	0.0345

The range of sheet thickness h for the sheared samples is also shown. Finally, K and n are the hardening law parameters for the two material grades as fitted to compression test data
