Effect of Separation on Strengths of Thermo-Mechanical Control Process Steel(Part2)

摘要

We had studied the effects of impact energy and impact speed on a quantity of separation occurred, and the distribution of in-plane fracture toughness in the TMCP steel plate with tendency to occur the separation. Moreover, we had dealt with the fatigue crack propagation on the specimen with surface notch and the specimen with through thickness notch at room temperature, and showed the anisotropic effect of thickness direction in the TMCP steel plate with tendency to occur the separation.
