Abstract:
A subsurface tool adapted to extend within a wellbore includes an integrally formed single-component body that defines an external surface and an internal chamber isolated from the external surface. When the tool is subjected to one or more stresses, a stress concentration is created within a stress zone of the single-component body, the stress zone being adjacent the internal chamber.
