fatigue cracking

基本解釋

Traditional fatigue mechanics only represents the stage before fatigue cracking of the AC layer.
傳統(tǒng)的疲勞力學(xué)只能反映結(jié)構(gòu)層出現(xiàn)疲勞裂縫前的階段。
In frequent bending stress condition, fatigue cracking occurred due to the cracking source had been initiated in welding heat affected zone.
在承受頻繁的彎曲應(yīng)力作用后，在其焊接熱影響區(qū)萌生了裂紋源進而發(fā)生疲勞開裂。
It was shown that there were two kinds of surface damages on the working surface of the die, i. e. the fatigue cracking caused by thermal stress and the hole caused by metallurgical defect.
結(jié)果表明，模具出現(xiàn)由熱應(yīng)力引起的疲勞裂紋和冶金缺陷引起的凹坑兩種表面損傷。

疲勞開裂
Fatigue cracking is one of main destruction forms of asphalt pavement.
疲勞開裂是瀝青路面主要結(jié)構(gòu)破壞形式之一。
疲勞裂紋
The buckling and ultimate strength of ship plating normally depend on a variety of influential factors, namely geometric / material properties, loading characteristics, initial imperfections(i. e. initial deflections and residual stresses), boundary conditions and corrosion, fatigue cracking.
船體板的屈曲和極限強度取決于很多影響因素，主要有：板的幾何尺寸、材料特性、載荷特征、初始缺陷(如初始變形和焊接殘余應(yīng)力)、邊界條件以及腐蝕的影響、疲勞裂紋等。
