fatigue crack resistance

基本解釋

The difference of mechanism between normal section fatigue crack resistance and static crack resistance for prestressed concrete members was analyzed.
針對(duì)預(yù)應(yīng)力混凝土構(gòu)件的正截面疲勞開裂機(jī)理與靜力開裂機(jī)理的差異。
Using one pass method the areas of partial stress concentration were laser-modified and the influence on fatigue crack initiation resistance was investigated.
研究無搭接激光單道掃描方式對(duì)材料局部應(yīng)力集中部位進(jìn)行表面改性及其對(duì)疲勞裂紋萌生抗力的影響。
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.
試驗(yàn)得出，殘余奧氏體可阻止疲勞裂紋的萌生和擴(kuò)展，提高沖擊疲勞抗力，降低沖擊疲勞磨損。
