- A notched specimen is designed to simulate the corrosion reaction at crack tip. 为此,文中设计了一种新颖的缺口试样,再现裂纹尖端的真实状态。
- Izod test.One of two tests (see also Charpy test) that may be used to measure the impact energy of a standard notched specimen. 悬臂梁式冲击实验:两种用于测量标准缺口试件冲击功实验的一种(另一种见Charpy test)。
- However, for AISI 316, hydrogen barely changed the fracture surface morphology of notch specimen in comparison with that in air. 然而,对AISI 316而言,和在空气中测试的试片比较起来,氢气几乎没有改变凹槽试片的破断面形态。
- For straight notch specimen, the crack propagation begins at the corner of the notch and the measured fracture toughness is dependent on the specimen geometry. 直槽切口偏离理想裂纹,裂纹起裂始于切口端部的角点,实测的断裂韧度值偏高且具有尺寸相关性;
- For the notched specimens, there are multiple crack initiation sites on the fractography. 瞬断区所承受的断裂应力随循环应力升高而降低;
- A frequency domain method for predicting the fatigue life of notched specimens under random vibration loading is presented. 提出了一个考虑应力集中和疲劳极限影响的缺口件频域随机振动疲劳寿命估算方法。
- For the same net-section stress, the notched specimens have a longer lifetime than the smooth specimen.This result confirms to P.Lukas' research. 在所研究范围内,切口对试样持久寿命的强化作用,得到他人试验的验证。
- The initiation and growth of part through and through cracks in blunt notched specimens of a medium carbon steel were investigated by a replication technique. 采用复型方法对中碳结构钢单边钝缺口试样的非穿透和穿透疲劳短裂纹的演化过程进行了研究。
- Fractographic observations showed that hydrogen could induce surface cracks for smooth specimens and a cleavage fracture pattern for notch specimens at RT. 破断面观察结果显示,在室温中,氢气会导致平滑试片在表面形成裂纹,而在凹槽试片中产生劈裂破坏形态。
- He is still a fine specimen of health. 他仍是健康的典范。
- The experiments on notched specimens of an Aluminium alloy indicat that the notch fatigue life can be increased by a tensile over-pre loading but decreased by a compressive over-pre loading. 预过载拉伸可提高铝合金缺口疲劳寿命,但效果不及喷丸;过载量太大还使寿寿命趋于子下降。
