Current methods for regularizing displacement fields in deformation-fitting problems are sensitive to rotation. We propose a rotation-insensitive regularization functional which is the true strain energy for a rubber-like material. The deformation-fitting problem is solved iteratively using successive approximations of the body's rotation, which may be non-uniform
