Computing image stress in an elastic cylinder
WebApr 1, 1974 · The generalized plane strain problem of the contact of layered elastic solids is reduced to an integral equation using Green’s function approach. Approximate numerical solutions are obtained by replacing the integral equation by a matrix inversion when the trapezoidal rule is used to represent the integral. WebWei Cai and Christopher R.
