Abstract
A strain sensing device is provided, which may include a hollow, cylindrical member having an inner surface and an outer surface. The outer surface may have an outer diameter corresponding approximately in size to an inner diameter of an inner surface of a cylindrical bore of a structural component configured to undergo mechanical loading. The hollow, cylindrical member may be configured to mate to the inner surface of the cylindrical bore of the structural component such that strain in the structural component is translated into strain in the hollow, cylindrical member. The strain sensing device may also include one or more strain sensing elements attached to the inner surface of the hollow, cylindrical member and configured to detect strain exhibited by the hollow, cylindrical member.
