Behavior of steel fiber–reinforced high-strength concrete at medium strain rate

Chujie JIAO, Wei SUN, Shi HUAN, Guoping JIANG

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 2,   Pages 131-136 doi: 10.1007/s11709-009-0027-0

Abstract: Impact compression experiments for the steel fiber–reinforced high-strength concrete (SFRHSC) at medium strainrate were conducted using the split Hopkinson press bar (SHPB) testing method.The experimental results showed that, when the strain rate increased from threshold value to 90 s , theincreased about 30%, the elastic modulus of SFRHSC increased about 50%, and the increase in the peak strain

Achieving High Strength and Tensile Ductility in Pure Nickel by Cryorolling with Subsequent Low-Temperature Short-Time Annealing

Zhide Li,Hao Gu,Kaiguang Luo,Charlie Kong,Hailiang Yu,

Engineering doi: 10.1016/j.eng.2023.01.019

Abstract: strength of 607 MPa and a uniform elongation of 11.7% were obtained after annealing at a small cryorolling strain(ε = 0.22), while annealing at a large cryorolling strain (ε = 1.6) resulted in ahardening during cryorolling, with an additional contribution from grain refinement and the formationcould be attributed to annealing twins and micro-shear bands during stretching, which improved the strainhardening capacity.
