We present in this investigation an advanced phenomenological approach combining the computational efficiency of classical plasticity models and accuracy high resolution multiscale crystal schemes. Within approach, a new constitutive framework has been developed implemented into ABAQUS/Standard finite element (FE) code. Compared to approaches, allows accounting for initial induced plastic aniso...

introduction: there is many ways to assessing the electrical conductivity anisotropy of a tumor. applying the values of tissue electrical conductivity anisotropy is crucial in numerical modeling of the electric and thermal field distribution in electroporation treatments. this study aims to calculate the tissues electrical conductivity anisotropy in patients with sarcoma tumors using diffusion ...

The effect of Ca and Zn in solid solution on the critical resolved shear stress (CRSS) basal slip, tensile twinning pyramidal slip Mg alloys has been measured through compression tests single crystal micropillars with different orientations. solute atoms increased CRSS for to ~ 13.5 MPa, while was lower than 85 reducing significantly plastic anisotropy comparison pure Mg. Moreover, CR...

Anisotropic hierarchical honeycombs of uniform wall-thickness are constructed by repeatedly replacing each three-edge vertex of a base hexagonal network with a similar but smaller hexagon of the same orientation, and stretching the resulting structure in horizontal or vertical directions to break the isotropy. The uniform overall thickness is then adjusted to maintain the constant average densi...

Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. In t...

Fibre reinforced plastic composite materials are difficult to machine because of the anisotropy and inhomogeneity characterizing their microstructure and the abrasiveness of their reinforcement components. During machining, very rapid cutting tool wear development is experienced, and surface integrity damage is often produced in the machined parts. An accurate selection of the proper tool and m...

Analysis of angular dependences the diffraction peak broadening observed in α-uranium as-received state, after loading by converging spherical shock wave, low-speed uniaxial deformation, and annealing at 850°С has been presented this work. Broadening anisotropy identical for all states investigated demonstrated. The authors have attempted to explain phenomena Young’s modulus uranium or crystall...

The present review paper consists of two main parts, which are not connected. first part is devoted to a general axisymmetric elastic–plastic plane stress solution, assuming polar anisotropy. Strains infinitesimal. principal trajectories coincide with the axes No restrictions imposed on yield criterion other than conventional criteria in plasticity. plastic portion strain rate tensor determined...
