对标准试样和辅助小尺寸试样与冲击功之间的变化规律进行了试验研究。结果表明:缺口形状相同而厚度不同的同一种材料的冲击试样,采用本文确定的试样厚度与试验温度的关系式,可使辅助小尺寸试样和标准试样的冲击试验数据直接换算,这对薄型材料的冲击试验具有重要的实用价值。
The experimental study was carried out on the variation of standard specimen and auxiliary small size specimen with impact energy. The results show that impact test data of the same material with the same notch shape and different thickness can be directly converted from the impact test data of the auxiliary small size sample and the standard sample by using the relationship between the thickness of the sample and the test temperature determined in this paper, This thin material impact test has important practical value.
