疲劳裂纹扩展检测 - 知乎 - 知乎专栏
网页fcgr 测试需要使用标准试样几何形状，包括紧凑拉伸 (ct)、单边缘缺口弯曲 (senb)、单边缘缺口拉伸 (sent) 和中心裂纹拉伸 (cct) 试样。astm e647 和 iso 12108 都接受这些试样几何形状并提供 k 解决方案。图 1 显示了 senb 和 ct 标本的几何形状，它们比其他两个更常用。

Se-糖基转移酶SenB在硒氨酸生物合成中的底物结合和催化机 …
网页唯一鉴定出的在硒烯氨酸生物合成中催化硒掺入的Se-糖基转移酶是来自Variovorax paradoxus的 SenB。 尽管SenB的生化功能已被研究，但其底物特异性、结构和催化机制尚未阐明。
Structures of SenB and SenA enzymes from - PubMed
网页2024年6月14日 · SenB and SenA are two crucial enzymes that form carbon-selenium bonds in the selenoneine biosynthetic pathway. To investigate their underlying catalytic mechanisms, we obtained complex structures of SenB with its substrate UDP-N-acetylglucosamine (UDP-GlcNAc) and SenA with N-α-trimethyl histidine (TMH). SenB adopts a type-B glycosyltransferase ...
Design of four-point SENB specimens with stable crack growth
网页2018年3月15日 · A four-point single-edge-notch-beam (SENB) test specimen loaded in displacement control (fixed grip) is proposed for studying crack deflection at bi-material interfaces. In order to ensure stable crack growth, a novel analytical model of the four-point SENB specimen in fixed grip is derived and compared with numerical models.
热固性树脂SENB韧性测量的开发,Polymer Testing - X-MOL
网页传统的单边缺口弯曲 (SENB) 断裂韧性测量是塑料材料的理想选择，但对于脆性热固性树脂而言，本质上很难引发足够尖锐的裂纹。. 在这项研究中，这个问题通过一个带有几何修改的 SENB 试样的即时扩展裂纹得到了解决。. 由于裂纹锐度自然、充分且可重复，因此 ...
