Expert Commentary
Refers to the specific Specimen Geometry No. 113, a high-precision contoured design. This geometry is intended to minimize stress concentrations at the transition from the grip to the gauge. Machining these specimens is difficult, and testing them requires Gas-Bearing or Hydrostatic grips to achieve the near-zero bending required by the standard. MTO’s Aerospace Graphite kit is specifically designed to meet the sub-1% bending requirements of this specimen class.
