A texture tensor to quantify deformations
نویسندگان
چکیده
Under mechanical deformation, most materials exhibit both elastic and fluid (or plastic) responses. No existing formalism derived from microscopic principles encompasses both their fluid-like and solid-like aspects. We define the statistical texture tensor to quantify the intuitive notion of stored deformation. This tensor links microscopic and macroscopic descriptions of the material, and extends the definition of elastic strain.

A texture tensor to quantify deformations: the example of two-dimensional flowing foams
In a continuum description of materials, the stress tensor field σ quantifies the internal forces the neighbouring regions exert on a region of the material. The classical theory of elastic solids assumes that σ determines the strain, while hydrodynamics assumes that σ determines the strain rate. To extend both successful theories to more general materials, which display both elastic and fluid ...
متن کاملPrediction of Instability in Planar Anisotropic Sheet Metal Forming Processes
In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...
متن کاملYoung’s modulus evolution and texture-based elastic–inelastic strain partitioning during large uniaxial deformations of monoclinic nickel–titanium
The authors draw upon recent first-principles calculations of monoclinic NiTi elastic constants to develop a combined numerical– empirical, texture-based approach for calculating the Young’s modulus of polycrystalline, monoclinic nickel–titanium specimens. These calculations are carried out for load direction inverse pole figures measured in situ via neutron diffraction during tension–compressi...

متن کاملPrincipal component analysis of shear strain effects.
Shear stresses are always present during quasi-static strain imaging, since tissue slippage occurs along the lateral and elevational directions during an axial deformation. Shear stress components along the axial deformation axes add to the axial deformation while perpendicular components introduce both lateral and elevational rigid motion and deformation artifacts into the estimated axial and ...
