摘要
报告了在不同的双轴载荷比和不同的裂纹倾斜角的情况下,表面裂纹疲劳试验的某些试验结果,并首次从裂纹扩展驱动力的角度,揭示了裂纹宏观疲劳断口的变化规律。
This paper reports some results of fatigue experiments on inclined surface cracks with different angles of crack inclination under various biaxial loading conditions. The variation features of fatigue-broken surface with biaxial loading ratio are revealed in the light of the crack driving forces.
