Connecting bolt which for a repeated stretching beyond the yield stress, is determined, consisting of– a bolt head (2),– a with a thread (6) provided with a shaft of the bolt (5) and– markings which are spaced axially from one another (9; 10) for displaying a permanent rotating ...
如果这种测试设备没有足够的容量,或者,螺栓或双头螺栓过长以致不能实物测试,标准圆形试样应使用小于满足表2中的“加工标本测试”的力学性能。
Yield strength is the amount of stress at which plastic deformation becomes noticeable and significant. Fig.1 is an engineering stress-strain diagram in tensile strength test. Because there is no definite point on the curve where elastic strain ends and plastic strain begins, the yield strength is...

The jaw type cement crusher has the advantages of simple structure, reliable work and convenient repair, the running cost is low, the body after the stress treatment residual, especially strong. Jaw crusher has a variety of forms, the principle is the same, namely th...
[22], one proposed by Hyer and Klang [20], which represents the stress field around a complete hole in a pin-loaded orthotropic plate, in order to model the behaviour of a complete connection. Hyer and Klang used the Conclusion It has been shown through experimental work that the stiffness...
aAccording to relative regulations, the maximum stress of not be larger than static yield limit[8]. Only when this principle is satisfied can the bolts be safe, that is 根据相对章程,最大重音不大于静态出产量极限(8)。 只有当这项原则是满意的罐头螺栓时是安全的,那是[translate]...
