縱裂紋 的英文怎麼說
中文拼音 [zōnglièwén]
縱裂紋
英文
longitudinal crack-
This indicated that the fracture had initiated at the unfused butt weld in the longitudinal stiffener.
研究表明裂紋是從縱向加勁助未熔透的對接焊縫中起始的。The cracks are primarily parallel to the longitudinal direction of the girder and to the nominal bending stresses.
裂紋基本上平行於主梁縱向，既平行於名義彎曲應力。The results show that : 1 ) the effects of interface on waves scattering are stronger in the structure with the interface perpendicular to the direction of fracture normal than that in the structure with the interface parallel to the direction of fracture normal. 2 ) when the interface is perpendicular to the direction of fracture normal, the amplitude of reflected waves and converted s - waves are higher and there are the sub - p - and sub - s - wave. 3 ) when the elastic waves propagating in the multi - stripe model, wavesforms become complex due to multiple scattering on interfaces
研究結果表明： 1 ）界面與裂縫排列方向平行時，界面對波的散射作用大於界面與裂縫排列方向垂直時的情況； 2 ）當界面與裂縫排列方向平行時，在界面上產生的反射波及轉換的橫波幅度較大，並且有次級縱波和橫波產生； 3 ）彈性波在多條紋結構中傳播時，在界面上產生多次散射使得波形十分復雜。Listed in column 2 are descriptions of the cracking.
第二縱列是關于裂紋的描述。In order to show the scattering and complex mode - conversion clearly, the total field is decomposed into longitudinal and transverse parts and the scattered field is obtained by subtracting incident wave from the total field
通過對縱橫波的分離和在全波場中對散射波的分離，清晰地顯示了裂紋對脈沖超聲波的散射和復雜的模式轉換。A small angle incidence longitudinal wave for sensitive evaluation of fatigue cracks

摘要對螺紋鋼筋由冷彎產生的縱向裂紋進行了分析，結果表明，硅酸鹽夾雜物分佈不均勻是造成螺紋鋼筋冷彎縱向裂紋的主要原因，並提出了相應的預防措施。Numerical simulation of crack detection in pipes using ultrasonic longitudinal guided - wave
管道超聲縱向導波裂紋檢測數值模擬Abstract : fatigue cracks in ship hull structures are most likely to occur in the highly stressed structural details. the conventional fatigue analysis is largely dependent on the determination of stress concentration factors ( scfs ) at the locations considered. this paper is concerned with the stress concentration of cutout in transverse web for longitudinal stiffener. a series of finite element models is carried out for the stress analysis of predefined structural details. the tabulated scfs of typical cutouts ( abs tanker rules ) in transverse web for longitudinal stiffeners are presented based on the finite element analysis ( fea ) results
文摘:疲勞裂紋往往發生在船舶結構的局部高應力區，而疲勞分析結果通常取決于任何準確確定結構的應力集中系數.本文研究為鋪設縱骨而在艙壁板上開孔的應力集中，採用有限元方法對預先給定的結構進行應力分析，基於有限元計算結果給出了艙壁板典型開孔（參見abs油船規范）的應力集中系數表2 ) the effects on waves conversion are stronger in rocks with dry fractures than that in rocks with water - filled fractures, and s - waves attenuate more rapidly in rocks with water - filled fractures. 3 ) the explosive point source which locates in anisotropic media can excites not only p - waves but also s - waves. 4 ) the properties of waves propagation were discussed and compared for several point sources with different source functions
結果表明： 1 ）平行排列裂縫造成的各向異性使波前變寬； 2 ）含乾裂縫巖石對波型轉化的影響比含充水裂縫巖石的大，橫波在含充水裂紋中傳播時衰減較快； 3 ）當介質存在各向異性時，爆炸點源產生的波不僅有縱波，還有橫波； 4 ）通過改變點源函數研究不同點源所產生波以及波型的轉換。The interaction effects between circular interfacial cracks or rigid line inclusions and a screw dislocation located either outside or inside inhomogeneity under antiplane shear, the electroelastic interaction between a piezoelectric screw dislocation located either outside or inside inhomogeneity and circular interfacial cracks and rigid lines under longitudinal mechanical and inplane electrical loads in linear piezoelectric materials and the elastic interaction between an edge dislocation located either outside or inside inhomogeneity and interfacial crack along a circular inhomogeneity are dealt with in this paper
