宏观裂纹 meaning in English
macro crack
macrocrack
macroscopic cracking
Examples
- Under load , the number of the micro - cracks increases ; the micro - cracks expand and eventually become macro - cracks , which result in the failure of the structure
在载荷作用下，微裂纹的数量增加，扩展最后变成宏观裂纹，从而导致结构的破坏。 - The grain - boundary cracks are found when the deformation of the strip is greater than a value , and these cracks will become marco cracks with the increase of the deformation
变形量过大时，冷轧薄带内部出现微观晶界裂纹，并随着变形量的增加最终发展成宏观裂纹。 - It is very important to study the correlation of cyclical strain on the side of hole with fatigue life cycle for understanding the material damage and micro - crack initiation , and for preventing macro - crack initiation and propagation
研究孔边循环应变与疲劳循环次数的相关性，对于研究材料损伤及微裂纹的产生，预防宏观裂纹的产生及扩展具有十分重要的意义。 - The material or structure used in practical engineering away have initial damage which gradually devepop from beginning of distortion to failure , in this process polymerization and development of micro - cracks will cause formation and expand of macro - cracks
在实际工程中使用的材料或构件及结构是存在初始损伤的，其从开始变形直至破坏，是一个逐渐劣化的过程，在这个过程中，微裂纹的聚合和长大造成了宏观裂纹的形成和发展。 - The results indicate that a stable deformation localization band occurs in the coal cutting course and develops to macroscopic crack ; the deformation localization band is slantwise ; while the cutter tooth is used , the deformation localization develops slowly , and the localization becomes wider and the strain value in the band area higher afterwards ; when the point - attack pick used the localization develops quickly and the localization band becomes narrow and the strain value in the band lower
研究表明：截齿截割煤体过程中，煤体出现稳定的变形局部化带，且最终发展为宏观裂纹；煤体变形局部化带为一个倾斜带：刀齿截割时，变形局部化发展较慢，但产生变形局部化后，局部化带宽且带内应变值较高；而镐齿截割时，变形局部化发展较快，但产生局部化后，局部化带窄且带内应变值不如刀齿高。
