局部应力集中 meaning in English
stress raisers
Examples
- The local stress concentration of the bus body frame was also studied
本文还研究了大客车车身骨架的局部应力集中问题。 - The main structure stress of the car body is particularly analyzed . it is analyzed and calculated under vertical load case , lengthwise stretch load case , lengthwise compression load case , air pressure power load case , operating load case . result shows : the structure distortion harmonize , strength - weakness positions represent local stress focus
通过对垂向载荷工况、纵向拉伸载荷工况、纵向压缩载荷工况、气动载荷工况和运用状态垂向载荷工况的分析计算,结果表明:该车钢结构变形协调,强度薄弱部位主要表现为局部应力集中。 - The fault controlled the magmatism and metallization relevant to the contact zone , and deformed successively and produced cataclastic rocks and two sets of joints ; the second stage was from late cretaceous to eocene . the fault zone deformed right - laterally under ne - sw striking transtention , and new joints zone was produced at the end of the two main faults because of local stress concentration . the fault produced inchoative cataclastic rocks , and two sets of typical joints in plutons ; the third stage of deformation was relatively faint and only a little of microcracks was produced and infilled with vei ns in the deformed rocks , which was during the himalayan movement
其后的继承性活动在断裂带内形成碎裂程度最强达到碎裂岩的碎裂岩系列构造岩,变形带两侧发育两组典型的共轭剪节理;第二次在晚白垩世?始新世,断裂在北东?南西向近水平挤压作用下右行张扭性活动,断裂带两主断裂在斜列重叠的端部由于局部应力集中进一步扩展形成节理带,而断裂在岩体区也发育两组典型的共轭剪节理,断裂内形成初碎裂岩为主的构造岩;第三次是喜山期以西侧抬升、东侧下降的强烈升降为主的活动,在基岩中,主断层两侧围岩出现微破裂。 - In harsh climate region , mere exists obvious local stress concentration near the upstream and downstream of the exposed - in - winter horizontal surface of the rcc dam , and the surface of spillway bucket though heat insulation is applied on the surfaces , tensile stress still exceeds the allowable one of concrete . this paper puts forward to adopt preset crack to avoid occurring more cracks . the special crack model is applied to simulate the dam preset crack , and the joint model of fracture mechanics is induced into strain - soften model
在结构措施方面,针对严寒地区高碾压混凝土重力坝坝体越冬层面的上、下游面附近及溢流坝堰面反弧段表面有明显的局部应力集中象现,在已采取一定的表面保温防护的条件下,拉应力仍然超过混凝土容许拉应力,开裂难以避免,进而提出设置碾压混凝土坝表面预留缝结构措施并对该措施进行深入研究,包括预留缝的扩展稳定和坝体沿预留缝的稳定性,以避免大坝在无措施部位开裂,解决大坝越冬层面水平施工缝的开裂问题。
