Dent Resistance of Cold-Rolled Low-Carbon Steel Sheet 730528

The dent resistance of cold-rolled low-carbon steel sheets is shown to be proportional to the product of the yield strength and the square of the thickness. However, the yield-strength value used in this relation must be the yield strength appropriate to the strain rate of the particular indentation process. The use of a yield-strength value obtained in a slow-speed tension test, for example, can lead to an erroneous estimate of the dent resistance of a sheet for an indentation process in which the strain rate is many orders of magnitude higher, as is usually true in commercial denting situations.
