DYNAMIC TESTS ON SELECTED 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.

Intermediate Strain Rate Testing of ASTM A992 and A572

    ASTM A572 50 specimens were fabricated from a domestic, nominal 0.375 in. thick plate. The mill test report (MTR) indicated that the plate also met the specifications of ASTM A709 50. ASTM A992 specimens were obtained from the web of domestic S12x31.8 beams, which had a nominal thickness of 0.35 in. The MTR for the A992 steel indicated the beam also met specifications of ASTM A6, A709 50, A572 50, and A36. The chemiSee more on icme.hpc.msstate.edu

    Stress State, Temperature, and Strain Rate Dependence of

    Manganese particle volume fractions represented 0.38–1.53% of the bulk material. Mechanical testing revealed a stress state dependence that showed a maximum strength increase of 85% from torsion to tension and a strain rate dependence that showed a maximum strength increase of 38% from 10 −1 to 10 3 s −1 at 20% strain. In tension, a negative strain rate sensitivity (nSRS) was observed in the quasi

    A36 steel Wikipedia

    A36 steel in plates, bars, and shapes with a thickness of less than 8 in (203 mm) has a minimum yield strength of 36,000 psi (250 MPa) and ultimate tensile strength of 58,000–80,000 psi (400–550 MPa). Plates thicker than 8 in have a 32,000 psi (220 MPa) yield strength and the same ultimate tensile strength of 58,000–80,000 psi (400–550 MPa).

    Structure property relationships of an A36 steel alloy

    Also, failure of an A36 I beam was examined in cyclic loads, and the crack growth rates were quantified in terms of fatigue striation data. Dynamic strain aging was observed in the stress strain behavior giving rise to an important point that there exists a critical temperature for such behavior.

    Dynamic hardening behaviors of various marine structural

    Few studies on the dynamic hardening behaviors of marine structural steels have been reported. HSE carried out tensile tests up to a strain rate of 10/s for marine structural steels equal to 355EM and 450ENZ, where EM or ENZ denote steel grade specified by British Standards. The test temperatures were RT and HT (100, 200, 300, 400, 450, 500, 550, 600, 650, and 700 °C).
