fatigue crack resistance

基本解释

The difference of mechanism between normal section fatigue crack resistance and static crack resistance for prestressed concrete members was analyzed.
针对预应力混凝土构件的正截面疲劳开裂机理与静力开裂机理的差异。
Using one pass method the areas of partial stress concentration were laser-modified and the influence on fatigue crack initiation resistance was investigated.
研究无搭接激光单道扫描方式对材料局部应力集中部位进行表面改性及其对疲劳裂纹萌生抗力的影响。
It is indicated that retained austenite in microstructure can inhibit the initiation and propagation of fatigue crack, improve the resistance to impact fatigue and decrease impact fatigue wear.
试验得出，残余奥氏体可阻止疲劳裂纹的萌生和扩展，提高冲击疲劳抗力，降低冲击疲劳磨损。
