用断裂韧度、缺口冲击试验评定钢的脆性倾向。
The brittleness tendency of steel has been assessed with fracture toughness and notch impact tests.
试验结果发现冻土的冲击韧度随冲量的增加而呈非线性增加趋势。
The results show that the impact toughness of frozen silt increases in nonlinear with the increase of pendulum impulse.
温度对冲击韧度的影响随冲量的增加而加大。 在试验温度范围内温度的影响远远小于冲量对冲击韧度的影响。
The influence of temperature on impact toughness increases with increase of impulse, and is quite smaller than the influence of impulse in the range of test temperature.
