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.
針對預(yù)應(yīng)力混凝土構(gòu)件的正截面疲勞開裂機理與靜力開裂機理的差異。
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材料局部應(yīng)力集中部位進(jìn)行表面改性及其對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.
試驗得出，殘余奧氏體可阻止疲勞裂紋的萌生和擴展，提高沖擊疲勞抗力，降低沖擊疲勞磨損。
