VEXTEC is honored to present at this year’s ASTM International Conference on Advanced Manufacturing (ICAM 2023), held October 30 – November 3 2023 in Washington D.C. VEXTEC’s CTO Dr. Bob Tryon is speaking on “Computational Fatigue Models to Assist in Risk-Based Certification of Additively Manufactured Metallic Parts” on November 1 at 4:00pm ET.
The presentation focuses on physics-based models to provide predictive analytics for certification in Additive Manufacturing (AM). The models integrate computational material engineering to simulate the costliest aspects of AM certification testing, reducing test repeats and significantly lowering the cost of certification. Statistical distributions of properties including microstructure, voids and surface roughness are used in the modeling, as well as structural finite element analysis and Monte Carlo techniques to simulate fatigue of a large population of components with complex loading. Simulated fatigue results are compared to laboratory fatigue testing data, and a standard work protocol is created for AM replacement of an aircraft engine throttle linkage component, and AM repair of foreign object damage to an aircraft engine airfoil.
