Abstract
A shank includes a captive portion, having a longitudinal central axis, a captive end, a first set of first structures, and a second set of second structure. The second set of the second structures is closer to the captive end than the first set of the first structures. The first set of the first structures has a first axial compliance coefficient along the longitudinal central axis. The second set of the second structures has a second axial compliance coefficient along the longitudinal central axis. The first axial compliance coefficient of the first set of the first structures is greater than the second axial compliance coefficient of the second set of the second structures.

A shank, comprising:
- a captive portion, comprising a longitudinal central axis, a captive end, a first set of first structures, and a second set of second structure, and wherein:
- the first structures extend away from the longitudinal central axis in a direction normal to the longitudinal central axis;
- the second structures extend away from the longitudinal central axis in a direction normal to the longitudinal central axis;
- ends of the first structures and the second structures, farthest away from the longitudinal central axis, form cylindrical surfaces that encircle the longitudinal central axis and equidistant from the longitudinal central axis;
- the first set of the first structures and the second set of the second structures are each half as long along the longitudinal central axis as the captive portion;
- the first set of the first structures and the second set of the second structures do not overlap along the longitudinal central axis;
- the second set of the second structures is closer to the captive end than the first set of the first structures;
- the first set of the first structures has a first axial compliance coefficient along the longitudinal central axis;
- the second set of the second structures has a second axial compliance coefficient along the longitudinal central axis;
- the first axial compliance coefficient of the first set of the first structures is greater than the second axial compliance coefficient of the second set of the second structures;
- at least one of the first structures consists of a first material;
- at least one of the second structures consists of a second material;
- the first material is different from the second material;
- any two adjacent ones of the first structures are separated by an empty gap;
- and
- any two adjacent ones of the second structures are separated by another empty gap.
A shank, comprising:
- a captive portion, comprising a longitudinal central axis, a captive end, a first set of first structures and a second set of second structures, and wherein:
- the first set of the first structures and the second set of the second structures are diffusion bonded together indirectly;
- the first structures extend away from the longitudinal central axis in a direction normal to the longitudinal central axis;
- the second structures extend away from the longitudinal central axis in a direction normal to the longitudinal central axis;
- ends of the first structures and the second structures, farthest away from the longitudinal central axis, form cylindrical surfaces that encircle parallel to the longitudinal central axis and equidistant from the longitudinal central axis;
- the first set of the first structures and the second set of the second structures are indirectly connected together;
- at least one of the first structures consists of a first material;
- at least one of the second structures consists of a second material;
- the first material is different from the second material;
- any two adjacent ones of the first structures are separated by an empty gap;
- and
- any two adjacent ones of the second structures are separated by another empty gap.
