In engineering, the term "stress" refers to: A. The internal resistance of a material to deformation B. The force applied to a material C. The change in shape of a material D. The rate of change of force 相关知识点: 试题来源: 解析 A ...
internal stresses/ internal stress fieldsstress reduction experimenteffective stressThe decomposition of stress applied on a material into two distinct parts called effective and internal stresses is often assumed but rarely experimentally measured. The strain-dip test technique, used occasionally in creep ...
As to the characteristics of the dynamic stresses, it was found that the radial stress near the shot point (γ<about 1.5m) acted as the nonoscillatory compressive stress and this wave shape was almost similar to that of the radial displacement, but at about 2 meters distant from the shot ...
internal stresses caused by the incorporation of nitrogen atoms in the crystal structures. The hardness measurements inFig. 4prove this, i.e., the hardness of the expanded martensite is over 1250 HV, while the expanded austenite layer has a hardness of 450 HV. It is known that the fcc ...
internal rotation result in forceful internal impingement [10]. 肩关节内部撞击,即在投掷运动倾斜阶段晚期,肩袖的下表面与关节后上盂唇和关节盂之间的撞击,被认为是肩袖后方损伤和 II 型SLAP病变的原因[50, 51]。肩内部撞击是生理性的,当肩关节处于外展外旋位时,无论是投掷肩和非投掷肩都会出现[52],而剧烈...

The U.S. government has often interfered in other countries' internal affairs by wielding the club of "human rights." However, the policy of separating migrant children from their families has severely endangered the migrants' lives, dignity, freedom and other human rights. The migrant and refuge...
Here we explore how the stress changes caused by the large 1969 Yangjiang earthquake are and if the stress changes induced by the main shock can explain the occurrence of the subsequent events in the study area. We firstly review the literature about the epicenter, focal mechanisms, and aftersho...
