According to the eigenstrain theory of micromechanics, described in the book by Toshio Mura (micromechanics of defects in solid, 1982) from page 15-20.
He provided the formulas for the eigenstrain at the core of screw and edge dislocation, but I can not understand completely.
Anybody can provide some reference articles about the gradient value du(i)/dx(j) at the core of screw and edge dislocations respectively?
