under pullout loads can be obtained. Meanwhile, a new variable named fabric anisotropy coefficient is introduced to evaluate the inherent relationship between macroscopic strength and microscopic fabric anisotropy. A correlation analysis is adopted to compare the accuracy between the newly-proposed coefficient and the most commonly used one. Furthermore, additional pullout tests on geogrid......

形机制为锥面滑移;沿挤压方向压缩时初始变形机制为拉伸孪晶,当变形量为0.08(8%)左右时由于孪晶消耗殆尽,变形变而以滑移的方式进行. 关键词:镁合金;各向异性;拉压不对称性;变形机制;高应变速率 中图分类号:TG146.2 文献标志码:A Anisotropy and asymmetry of as-extruded AZ31...) Abstract: The anisotropy and asymmetry of an as-extruded AZ31 magnesium alloy deformed under high strain rate were investigated by split Hopkison tension (SHTB) and pressure bar (SHPB). The reasons......
relationships induced by the different loading methods were investigated. A remarkable stress-induced anisotropy under complex stress state was observed. Contrary to popular assumptions in traditional... analysis and constitutive models do not give serious consideration to the intermediate principal stress and anisotropy effects in soil rock built structures. Key words: true triaxial test; stress induced......
and properties(including mechanical properties, thermal stability and anisotropy) of 2197Al-Li alloy was studied by tensile test and TEM. The results indicate that 2197 alloy is an alloy with moderate strength, little anisotropy and better thermal stability. 2197 alloy can obtain the optimistical combination of the strength and ductility in T8 temper. The major strengthening phases are a few δ......
