Generalized Gradient-Dependent Plasticy Theory [PDF]

Advanced Materials Research, 2011
Based on the Generalized Plastic Mechanics (GPM) and strain gradient-dependence of yield surfaces, the differential expressions of the volumetric and shear plastic strains are constructed, then the Generalized Gradient-dependent Plastic Mechanics (GGPM) is established to describe the strain localization characteristics and the basic mechanics ...

A singular semilinear problem with dependence on the gradient

Journal of Differential Equations, 2016
Abstract In the present paper we study the problem of finding classical and weak solutions for a semilinear elliptic equation involving a singular term and a nonlinearity depending on the gradient. The approach we follow, based on a suitable combination of sub–supersolutions techniques and fixed point theory, is not quite the same in the two cases ...

Dependence of the Depolarization Tensor on the Displacement Gradient [PDF]

Canadian Journal of Physics, 1971
Expressions are given for the first- and second-order derivatives of the depolarization tensor with respect to the displacement gradient. The results are applied to the special case of the sphere.

Gradient direction dependencies in natural images

Spatial Vision, 2007
We have used information-theoretic measures to compute the amount of dependency which exists between two and three gradient directions at separate locations in an ensemble of natural images. Control experiments were performed on other image classes: phase randomized natural images, whitened natural images and Gaussian noise images.
