疲劳断裂力学 meaning in Chinese

fatigue fracture mechanics

Fatigue fracture mechanics
疲劳断裂力学
But , for the reflective cracking of asphalt pavement with half rigid base course and the cracking of the ac overlay above joints ( cracks ) in existing pcc pavement , the results of research show that the fatigue life of ac layer is mainly the life of the crack propagating stage . so the theory and method of fatigue destructive mechanics ( fatigue fracture mechanics and fatigue damage mechanics ) should be used to study and design the pavement structures instead of traditional fatigue mechanics
而对于半刚性基层反射裂缝和旧水泥混凝土路面沥青混凝土加铺层接缝(裂缝)开裂，研究发现，沥青结构层的疲劳寿命主要为裂缝扩展阶段的寿命，此时不应采用传统的疲劳力学进行研究和结构层设计，而应采用疲劳破坏力学(疲劳断裂力学和疲劳损伤力学)理论与方法。
