punch test

The results show that the SPT load displacement curves of BMG are very sensitive to punch velocity and test temperature, and the shape of SPT load displacement curves is controlled by strain rate sensitivity, viscosity and punch velocity etc.

结果表明，BMG材料的SPT载荷位移曲线对压头速度和实验温度的敏感性较高，而SPT载荷位移曲线的形状与材料的应变速率敏感系数、粘度、压头速度等因素有关。
