A new method of calculating the internal stress distributions in wound reels of magnetic tape using a finite-difference approach is presented. A functional representation of the nonlinear radial elastic modulus is used to model reel behavior more accurately. Procedures are described to measure the radial elastic modulus and radial Poisson’s ratio. It is shown, by comparison to experimental data, that the method accurately predicts in-roll stress distributions.
