Bonding method and apparatus (20) comprises one or more selected target having binder material web (26) conveyed through the at least one pair of jaws rotating with the bonding rolls (32, 34) between the region (30), thereby forming a bonded web and produce (28). 在一个特定的方面中,...
An investigation of shear deformation in a semi-solid state of a high strain rate superplastic Si3N4p/Al-Mg-Si composite[J].Langmuir,1998,(15):7260-7266.doi:10.1016/S1359-6454(98)00223-7.MABUCHI M,IWASAKI H,HIGASHI K. An investigation of shear deformation in a semi-solid state of a ...
Grain rotation or pile- up assisted grain rotation [30] in soft grains may dominate whole plastic deformation of 174/[536] J. Y. Xie et al. Figure 5. Schematic diagram of formation mechanism of shear bands in the Al/W multilayers (a) not loading state (b) the first stage of loading...
The use of low strain rate is now a widely used technique in evaluating the response of material against stress. This must be carefully studied and implemented in the field in order to generate accurate outcomes. The strain rate can be determined by the formula: Strain Rate = Change in Strai...
In this work, a new rate-dependent interface model for computational analysis of quasi-brittle materials like concrete is presented. The model is formulated on the basis of the inviscid elastoplastic model by [Carol, I., Prat, P.C., López, C.M., 1997. “A normal/shear cracking model. ...
1a,b. In the tests, both ends of the specimens were fixed by the chuck of the testing machine. The lower chuck was moved downward at a rate of 2 mm/min under the control of the testing machine to achieve tensile and shear loading. A static strain analysis system was used to acquire ...
effects on the stress-strain behaviour of geomaterials, the viscous properties of a poorly-graded relatively angular quartz-rich sand, Toyoura sand, under air-dried conditions, were investigated by performing a comprehensive series of direct shear (DS) tests at a fixed normal stress equal to 50...
of the dislocations move at a speed approaching the shear wave velocity28. Under shock loading at super high strain rates, dislocation homogeneous nucleation plays an important role in dynamical plasticity29,30. 3D-DDD simulations were also employed to study shock deformation in silicon crystals ...
(1994). probed swirling motions in cells packed with spacers by syringing pigment at a Reynold number of 200. The influence of flowrate on the spread of heat polarization and shear stress in MD modules was investigated by Shakaib et al. (2012). Lacey (1980) examined the effect of flow...
A better control of the precursor textural properties during the precipitation could thus lead to original properties on the final support. Moreover, this reasoning could also apply on ammonium dawsonite (also called ammonium aluminium carbonate hydroxide or AACH, with formula NH4Al(OH)2CO3), an...
