本文提出了一个改进的等截面双悬臂试样恒位移处理模型。基于此种增大的双悬臂梁恒位移模型,提出等截面双悬臂试样在恒位移条件下为恒K试样,并计算了4340钢的断裂韧性值。
In this paper, an improved constant displacement dual-cantilever specimen model is proposed. Based on this model of constant displacement of double cantilevers, a constant K specimen with constant cross section and double cantilever specimens was proposed and the fracture toughness of 4340 steel was calculated.
