Instrumented nanoindentation and 3D mechanistic modeling of a shale at multiple scales
Anisotropy Creep FIB-SEM Heterogeneity Nanoindentation Shale
2015/7/1
Nanoindentation tests, spanning various length scales ranging from 200 nm to 5 lm deep, were performed on a sample of organic-rich Woodford shale in both the bedding plane normal and bedding plane par...
Mapping the initiation of plastic deformation in nanoindentation
plastic deformation nanoindentation
2010/11/17
Under the inhomogenous stress field set up by nanoindentation, the smaller the extent of the stress field the greater the yield pressure. When the specimen contains a thin layer of softer material, th...
东方蝼蛄前足爪趾结构与表皮纳米力学性能（Microstructure and Nanoindentation Properties of Foreleg’s Tarsal Claw of the Oriental Mole Cricket (Gryllotalpa orientalis Burmeister)）
东方蝼蛄 爪趾 微观结构
2009/8/11
利用扫描电镜分析了东方蝼蛄前足爪趾表面及断面几何结构特征，得知东方蝼蛄前足爪趾具有中空结构，断面材料呈层状复合结构。利用切片法分析了前足爪趾中空结构。利用纳米力学测试系统对东方蝼蛄前足爪趾表皮材料进行了测试，可知东方蝼蛄爪趾内侧的弹性模量和纳米硬度明显高于其爪趾外侧。与已有研究结果比较表明，东方蝼蛄爪趾表皮的纳米硬度高于臭蜣螂、粪堆粪金龟、弧齿爪鳃金龟的前足胫节表皮的纳米硬度，并高于牛蹄、羊蹄和猪...
Rate-dependent serrated flow and plastic deformation in Ti45Zr16Be20Cu10Ni9 bulk amorphous alloy during nanoindentation
nanoindentation AFM TEM metallic glass
2010/10/12
The plastic deformation of Ti45Zr16Be20Cu10Ni9 bulk metallic glass has been investigated by
nanoindentation performed with loads ranging from 10 to 200mN in a wide range of loading
rates. The plasti...
