LSAW pipe breaks, hydraulic (pneumatic) components are designed with mechanical properties, brittle fracture is also related to the temperature of components.


It is found that when the temperature is lower than a certain value, the data will become brittle and the shock absorption capacity will decrease significantly. This phenomenon is called low stress brittle fracture in the process of cold brittleness and high strength metal materials. There are cracks in heterogeneous isotropic structure, inclusions and voids in the data structure. All these defects can be regarded as microcracks in materials. Therefore, the appropriate cold-brittle transition temperature data should be selected according to the components of working temperature.

It is generally considered that the data are uniform, and the continuum isotropy based on this analysis method is considered to be a safety design, sometimes an accidental rupture.


Brittle fracture is caused by a variety of reasons, such as: precipitates on grain boundaries, whether their strength is stronger than the strength or weakness of matrix, are the cause of cracks; segregation of inclusions in grain boundaries is also the cause of fracture; in addition, even when the alternating load is far less than the yield limit, fatigue fracture will also occur.
