冲击拉伸试验 meaning in English
repeated impact tension test
Examples
- Tensile tests of carbon filament yarn shows at high strain rate that the mechanical behavior of carbon fiber bundles are insensitive to strain rate , i . e . , the failure stress strain and elastic modulus are not increased with the rising of strain - rate . however , the fractograph of carbon fiber is rate - dependent . the fractograph of carbon will become smooth from coarse as the strain rate increases
通过对碳纤维束的冲击拉伸试验表明，虽然碳纤维束的力学性能与应变率基本上是不相关的，即随着应变率的增大，碳纤维束的初始模量、破坏应力及其失效应变都变化不大，但碳纤维束的破坏断口与冲击拉伸实验的应变率密切相关。
