The general critical-state model, which includes the effects of both flux-line cutting and flux pinning, is used for calculating the response of a type-II superconducting cylindrical shell subjected to applied magnetic fields that change in both magnitude and orientation. Analytic expressions for the ac losses are obtained for the case that the applied field has a small-amplitude oscillating component. For the regime of partial penetration of the changing {bold B} field, the ac-loss expression reduces, for large cylinder radius, to that in slab geometry. When full penetration occurs, the ac-loss expressions depend upon the cylinder outer radius.
