裂纹

• The yield zones he found in polycabonate were slits extending ahead of the crack .
  他发现聚碳酸脂中的屈服区是延伸至裂纹前沿的长条裂缝。
• All existing web cracks were arrested by drilling 19 mm holes at the ends of the cracks .
  所有已存在的腹板裂纹都在裂纹端部钻19mm的孔止裂。
• The compliance-calibration specimen has a slot of finite-tip radius in place of a crack .
  柔度算定试样是用一个有限端部半径的槽来代替裂纹。
• Typical butterfly-fringe pattern associated with crack tips can be seen in this figure .
  在此图中可以看到与裂纹顶端有关的典型的蝶形条纹图。
• The crack near midspan is more clearly represented by the predicted behavior for stage 1 .
  跨中附近的裂纹用阶段1所预期的特性来表示更为恰当。
• The crack between the coped and hole was removed by air arc and then repaired by welding .
  在修割边和钻孔之间的裂纹用气弧消除，然后进行焊补。
• Moderately weathered rock showed more intense bleaching and fissuring in the feldspars .
  中等风化岩石则是指长石有更为强烈的变白现象和裂纹现象。
• Sometimes the density of crazes is sufficient to give the stressed plastic a milky appearance .
  有时小裂纹密度很大，使受应力的塑料外观呈现乳白色。
• The smaller the curvature and the larger the crack length the smaller will be the fracture stress .
  曲线半径越小，裂纹长度越大，断裂应力也就越低。
• The ground area was also checked with dye-penetrant to ensure that no crack tip remained .
  打磨区也用着色渗透剂进行了检查，以便确保无裂纹尖端留存。
