An inverse solution for winding stresses in wound coils of linear orthotropic material with large deformations

Abstract

This paper extends a previous analysis of determining the winding stress in coils, using an inverse solution approach to coils with large deformations of linear orthotropic materials. This approach has the advantage of determining the required winding stress profile explicitly once the desired residual stresses in the coil to avoid post-winding defects are known. Comparisons between the theories for small and large deformations are also made, with coil properties, where the small deformations assumption is inappropriate, are identified.
