LSAW pipe fracture, hydraulic (pneumatic) parts in mechanical performance design, brittle fracture is also related to the temperature of parts.


It is found that when the temperature is lower than a certain temperature, the data will change to brittle state and the impact absorption power will decrease obviously. This phenomenon is called low stress brittle fracture in this process. In cold brittle and high strength metal materials, there are cracks in non-uniform isotropic tissue in the data organization, as well as inclusions and pores. All these defects can be regarded as micro cracks in materials. Therefore, the design time should be selected according to the components of the working temperature to select the appropriate cold brittle transition temperature data.

It is generally considered that the data are homogeneous, continuous and isotropic. According to this analysis method, it is considered safety design, and sometimes it will crack unexpectedly.


Brittle fracture is caused by a variety of reasons, for example, the precipitates on the grain boundary are the causes of cracks, whether their strength is stronger than the strength of the matrix or the weakness. The segregation of inclusions in the grain boundary is also the cause of fracture. In addition, even when the alternating load is far less than the yield limit, it will cause fatigue fracture.
