Figure 1 – Atomic lattice inside a grain: 3D unit cell (left), 2D section along the basal plane inside a grain (center), the 3 slip systems we take into account (right)
Figure 2 – Shear load on the 30 grain polycrystal: averaged microscopic stress (left), macroscopic stress (right).
Table 1 – Values of K M for different polycrystals with different loadings (the indicated value is the average on different boundary condition values).
Figure 3 – Evolution of  ˜ σ µ yy  g as a function of  (ε vp µ ) yy  for the 30 grain polycrystal, tension-compression-shear load ( ·  g is the average over the grain).

Thus, the effective stress of a quadriphasic medium can be derived from a regular strain energy function, which physically has the same meaning as in single phase or biphasic media,

So, when compared with the classical deep bed filtration model (1.1), the advective term in the population balance equation (4.31) for intermediate size particles contains an

Each grain of a ferromagnetic polycrystalline material is divided into domains (figure 3) that are magnetised at saturation, whatever the external magnetic field (Bozorth, 1951).

The microforce balance, augmented with suitable constitutive information, yields: a kinetic equation for the microstructural field; criteria for both cohesion decreasing (damage

We can understand the pseudoelastic behavior (i.e. mechanical hysteresis but no residual strain when the high temperature austenite phase is subjected to an external stress) based

Recently, there has been significant progress in the direction of discrete crack growth modeling – the development of a partition of unity finite element method for crack

This book includes articles on a broad range of inverse problems including in- verse scattering, inverse problems for the radiative transfer equation, the in- verse problem

The main originalities of the model are first related to the explicit description of evolving heterogeneities of the dendritic structures and their consequences on the derivation
