On the wedge dispiration in an inhomogeneous isotropic nonlinear elastic solid

In this short note we find the stress field of a wedge dispiration (a combination of a screw dislocation and a wedge dislocation along the same line) in an inhomogeneous incompressible isotropic nonlinear solid. We discuss the effect of the radial inhomogeneity of energy function on both the stress field and the energy per unit length of the dispiration and compare with those in an isotropic linear elastic solid.
