ABSTRACT:
A downhole tool string component has a tubular body with a first and second end. At least one end is adapted for axial connection to an adjacent downhole tool string component. A covering, secured at its ends to an outside diameter of the tubular body, forms an enclosure with the tubular body. The covering has a geometry such that when a stress is induced in the sleeve by bending the downhole tool string component, that stress is less than or equal to stress induced in the tubular body. The covering may be a sleeve. Further, the geometry may comprise at least one stress relief groove formed in both an inner surface and an outer surface of the covering.
