One is called the S-N curve of surface fracture mode. It is governed by a crystal slip on the specimen surface, which occurs in the region of short fatigue life and high stress amplitude level.
一组叫做表面破坏模式的S-N曲线,它发生在高应力幅短寿命区,是由试样表面晶体滑移引起的。
Based on this, SRM "s pressure, thrust, mass flow rate and their integration sum are predicted with correlation parameters of random specimen and standard motor."
