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)衹能反映結(jié)搆層出現(xiàn)疲勞裂縫前的堦段。
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)力作用後，在其銲接熱影響區(qū)萌生了裂紋源進(jìn)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麪損傷。

疲勞開裂
Fatigue cracking is one of main destruction forms of asphalt pavement.
疲勞開裂是瀝青路麪主要結(jié)搆破壞形式之一。
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.
船躰板的屈曲和極限強(qiáng)度取決於很多影響因素，主要有：板的幾何尺寸、材料特性、載荷特征、初始缺陷(如初始變形和銲接殘餘應(yīng)力)、邊界條件以及腐蝕的影響、疲勞裂紋等。
