• An additional experiment is performed , and the weld specimens and heat effected zone specimens of dh36 steel are researched , through which the outcomes from the formulas of the standard and from other formulas is compared , which demonstrates the validity of standard test means for ctod and j - integral
  另外还进行了一个附加试验，对具有不同尺寸的dh36钢的焊缝试样和热影响区试样进行了研究，将本文所用标准中公式的计算结果与其它经验公式的计算结果进行了对比，进一步证明了ctod和j积分标准试验方法的有效性。
