6) angle of crack departure from normal
裂纹偏角
1.
There are medial crack, lateral crack and subsurface crack on the typical crack photos, and these cracks are departure from normal of indentation surface, and also the mark of angle of crack departure from normal (namely α c) and angle of medial line of wedge departure from normal (namely α a )is same.
试验表明 :加载裂纹的偏角αc 与楔角对称线偏角αa 总是符号相同 ;对于形状相似的压头 ,楔角对称线偏角越大 ,裂纹偏角也越大 ;对双斜压头而言 ,如果楔角不等 ,但楔角对称线偏角相等 ,裂纹偏角仍大致相等。
补充资料：三角韧带
三角韧带
triangular ligament
位于肝脏膈面背侧左、右两角的腹膜返折增厚形成的韧带。左侧的称左三角韧带，右侧的是右三角韧带。它们分别是左、右冠状韧带前后两层延伸会合而成，与横膈相连。这两条韧带较坚韧。左三角韧带内常有血管及迷走胆管，右三角韧带内也有血管，因此，切断时应当给予结扎或缝扎。
