Formation and Development of Shear Bands inGranular
نویسندگان
چکیده
A system of equations modeling antiplane shear in a granular material is considered. The model includes the possibility of localization of strain, and the subsequent development of shear bands. This behavior is captured in our analysis of the Riemann initial value problem, in which an initial discontinuity propagates as a combination of moving waves and a stationary shear band. The analysis is veriied by numerical results obtained with a Godunov method including adaptive mesh reenement.

Shear Localization due to Strain Softening in Side Pressed Cylinders
In this paper, shear localization due to strain softening in sidepressed cylinders, is inverstigated. Shear localization causes formation of macroscopic shear bands which can be obsserved in the metallographic cross-section. In this paper, for the first time a method is presented in which a simple two-slice model is used to study the formation of shear bands. The results obtained form this mode...

متن کاملLinear analysis of melt band formation by simple shear
Recent experiments by Holtzman et al. [2003] demonstrate that partially molten aggregates of many mantle materials undergoing simple shear (from ∼ 100−500% strain) will spontaneously develop localized melt-rich bands. These bands develop at small strains but persist at low angles to the plane of shear (∼ 15– 20) even at large shear strains. The melt-rich bands also appear to form localized weak...
متن کاملبررسی عددی تأثیر خصوصیات خاک بر باندهای برشی
In some natural events such as soil failure the deformations are localized in narrow restrictions, which are called shear bands. This event which is a fundamental phenomenon in granular material, has been widely investigated during recent decades within expensive experimental tests and also some numerical simulations. Most of previously used numerical methods are based on continuum theories des...
متن کاملIn situ transmission electron microscopy studies of shear bands in a bulk metallic glass based composite
In situ straining transmission electron microscopy (TEM) experiments were performed to study the propagation of the shear bands in the Zr56.3Ti13.8Cu6.9Ni5.6Nb5.0Be12.5 bulk metallic glass based composite. Contrast in TEM images produced by shear bands in metallic glass and quantitative parameters of the shear bands were analyzed. It was determined that, at a large amount of shear in the glass,...
