刊名:Journal of the Mechanics and Physics of Solids 2006年第1期 摘要:First, Eshelby's driving force for the motion of a sharp interface is rederived from general thermodynamic principles. Ferroelectric and ferroelastic domain walls represent a special class of such interfaces in mechanica...
Journal of the Mechanics and Physics of Solids Strain gradient solution for the Eshelby-type polyhedral inclusion problemGao, XLiu, M Q
It is clear that to obtain such jumps in plastic flow and PT rates in some rare cases, a theory should contain singularity that strongly depends on some external conditions. To resolve the problem, we will utilize the main concept of high-pressure mechanochemistry16,17,18,19. Our first point...
Despite the significance of surface effects on the deformation behaviours of small-scale metallic glasses, systematic investigations on surface states are lacking. In this work, by employing atomistic simulations, we characterise the distributions of loc
The Eshelby-type problem of an arbitrary-shape polygonal inclusion embedded in an infinite homogeneous isotropic elastic material is analytically solved using a simplified strain gradient elasticity theory (SSGET) that contains one material length scale parameter. The Eshelby tensor for a plane strain inc...
Blanton…While the suite of programs is intended for the analysis of any diffraction pattern, particular attention was focused on the analysis of common amorphous, non-crystalline or partially crystalline materials found in minerals, polymers and pharmac… USE OF A BE-DOME HOLDER FOR TEXTURE AND ...
This work attempts to construct models which can describe the size effects in modulus and hardness of polymers measured by indentation tests. Firstly, the origin of size effects in the procedure of nanoindentation is analyzed. The finding of the literature that the indentation size effects of polyme...
刊名:Journal of the Mechanics and Physics of Solids 2019年第9期 摘要:Configurational, or Eshelby-like, forces are shown to strongly influence the nonlinear dynamics of an elastic rod constrained with a frictionless sliding sleeve at one end and with an attached mass at the other end....
The strain concentration factors can be determined by solving the Eshelby inclusion problem [22]. For instance, if we consider a granular morphology, then the homogenized solid is the reference phase, and the strain concentration tensor of the porous phase is defined by: 〈𝔸𝐼〉𝑉𝜙=...
The unit cell (Figure 1a) is discretized in 128×128×128128×128×128 voxels and contains a square-shaped inclusion discretized in 32×32×132×32×1 voxels corresponding to an Eshelby-like square prismatic loop perpendicular to the z-axis. In order to generate a shift of the upper surface...
