The disclosed invention is a novel method for constructing a Torsional Vibration Damper (TVD). The traditional means used to construct the hub of the TVD was to employ a single material. The disclosed invention essentially discretizes the construction of the TVD hub into three regions: nose, spokes, and flange, and simultaneously aligns unique materials and manufacturing methods for each region with the structural loads borne thereby. Consequently, the invention helps in reduces four unwanted characteristics: (1) mass; (2) polar mass moment of inertia; and (3) casting scrap; and (4) cost. Furthermore, because of this construction other enhancements to the axial and angular structural integrity of the TVD can be reaped in certain cases.
