. In bending-mode test, it is difficult to apply a large strain on a thin-film of a ductile material and a stress gradient occurs, causing non-uniform stress distribution across cross section. A bulge test can...

. To describe this tendency of effective strain distribution along the radial direction quantitatively, the variances of effective stain gradient with the thickness from the inner surface to the outer... the rotation rate is large, the strain gradient (in Figure 5) of the experiments (such as Experiment No. 3, 6, and 9) is relatively small on different cross sections. Accordingly, this is advantageous......

Key words: surface mechanical grinding treatment; commercially pure titanium; gradient nano-to-micron grain; strain hardening; dimple 1 Introduction Grain refinement to submicron... between the coarse-grained matrix and the gradient nano-grained surface layer. Generally speaking, dimple size is affected by the second phase and strain hardening capacity of metals. There is no inclusion......
the compressive strength and modulus of the multi-layered gradient HA/PVA gel biocomposites increased exponentially with the rise of compressive strain ratio.Both the compressive strength and average...Compressive Mechanical Characteristics of Multi-layered Gradient Hydroxyapatite Reinforced Poly(Vinyl Alcohol) Gel BiomaterialYusong Pan,Qianqian Shen,Chengling Pan,Jing WangSchool of Materials......
. The PLC effect of 5182 Al alloy could be effectively postponed by the formation of gradient nanostructure after SMAT. It leads to the increase of critical strain of the PLC effect, more concentrated distribution of serrated strain, and increase of average stress amplitude in special strain range. The influence of grain size and gradient nanostructure on the PLC effect of 5182 Al alloy was also......
