DYNAMIC TESTS ON SELECTED STRUCTURAL STEELS

Abstract

Dynamic tension tests and static tension tests were conducted on four grades of structural steels. The steels conform to ASTM grades A36, A242, A441, and A572. Stress-strain curves are presented for each steel at various strain rates, ranging from static to about 1.5 in./in./sec. While all steels showed an increase in yield stress with increasing strain rates, the A36 steel showed the greatest increase. Design recommendations are given for structural steels subjected to high strain rates. Additional specimens were strain aged, and stress-strain curves were obtained for both dynamic and static tests. Of the strain-aged steels, only the A36 steel showed a significant increase in strength over the non-strain-aged steels, when loaded dynamically. No adverse effects of strain aging were noted on any of the steels.
