Buried flaw was found in FCB weld. CTOD test was performed on the weld sample.

用FCB法对船板钢进行焊接试验，发现在焊缝中存在内埋裂纹。

The CTOD toughness can be used as the basis to amend the conventional impact toughness criterion.

CTOD性能可作为修订常规冲击韧性标准的依据。

The dynamic plastic fracture toughness CTOD and its variation with different. crack propagation speeds.

塑性动态断裂韧性CTOD，及其在不同裂纹扩展速度下变化规律的测试。

It has been shown that many properties of structural steel varies with temperature, so the change of temperature will also change the value of CTOD.

结构钢材的相关力学指标随着温度发生变化，因此温度变化也会改变CTOD的数值。

The results indicate that the shapes and positions of the CTOD design curve are greatly affected by the welding residual stress and the strength mis-matching.

结果表明，强度组配和残余应力对CTOD设计曲线具有明显的影响；
