查询词典 parent metal

It is found that the design of reinforce-beam section dog-bone connection can transfer the yielding joint from flange welds to parent metal zone, which possesses better plasticity and avoid yielding joints in weak welds. This design also enables beam flanges to dissipate earthquake energy more effectuality and protects weak welds.

在弹性、弹塑性有限元分析的基础上，对狗骨式节点和翼缘增强狗骨式节点进行了承载能力对比分析，结果表明：翼缘增强狗骨式节点设计可以将梁柱翼缘焊缝的塑性铰有效的转移到塑性好的母材区域，避免了在薄弱的焊根部位形成塑性铰，保护了韧性较差的焊缝。

The test result shows that fatigue crack rate in welding line area is greater than that in parent metal when crack stress intensity factor amplitude △K is greater than 20 Mpa,but there is no more difference.

试验结果表明，在应力强度因子幅△K＞20Mpa后疲劳裂纹在焊缝区的扩展速率比在母材的大，但两者差距并不悬殊。

It is found that the design of dog-bone connections can transfer the yielding joint from flange welds to parent metal zone, which possesses better plasticity and avoid yielding joints in weak welds.

本文在弹塑性有限元分析的基础上，对普通节点和狗骨式节点进行了耗能能力对比分析，结果表明：狗骨式翼缘削弱设计可以将梁柱翼缘焊缝的塑性铰有效的转移到塑性好的母材区域，避免了在薄弱的焊根部位形成塑性铰，保护了韧性较差的焊缝。
