FOR IMMEDIATE RELEASE:

BRENTWOOD, Tenn., April 28, 2020—VEXTEC® Corporation in Nashville, TN, has been awarded a small business innovative research (SBIR) contract, supported by Aerojet Rocketdyne, to develop an additive manufacturing certification framework for Air Force applications, with the objective of accelerating the qualification and adoption process for new additive manufactured materials, augmenting the traditional verification process with a model-informed software tool called VPS-MICRO®.

The VEXTEC developed software, VPS-MICRO, is an Integrated Computational Material Engineering (ICME) based tool that predicts the risk of cyclic fatigue failure of an additive manufactured metal part based on the location specific microstructure, defects, residual stress and surface roughness. Using the software eliminates unsuccessful design options early in the design processes. Also, the software greatly reduces the test cost and time needed to determine the statistical confidence in the certified lifetime instead of having to acquire a large population of fatigue tests needed to do the same.

“We are leveraging real word data we’ve collected like fatigue strength and microstructure to create a digital model that can be used to predict the critical fatigue failure points of a component and simulate how surface features affect overall component strength,” said Dan Matejczyk,  Materials and Process Engineer,  Aerojet Rocketdyne. “The goal is to have a mix of physical test data combined with virtual data to accelerate the qualification process. Aerojet Rocketdyne will provide years of historical test data and VEXTEC will provide the software modeling capability.”

Rapid and reliable part qualification is necessary for additive manufactured components to realize their potential benefits. However, variability in microstructure and surface features may be significant, and must be managed for assured reliability. This program’s certification framework, methods and tools will assure component performance and reliability while enabling additive manufacturing schedule and cost advantages.

Aerojet Rocketdyne, a leader in additive manufacturing for more than a decade, will support VEXTEC in incorporating the additive manufacturing certification with computational fatigue models into a standard work process.

Jeff Haynes, Additive Manufacturing Program Manager at Aerojet Rocketdyne, noted that “With regard to additive manufacturing, we need to answer questions like: Where does modeling fit into the certification process? What is the best mix of analysis and testing? What are viable near-term solutions and what are the long-term goals for computationally enhanced certification processes that will be useful in the broader aerospace industry to produce highly-reliable parts.”

VEXTEC’s SBIR technology transition plan (STTP) for its current Phase II work involves further maturing of its VPS-MICRO software to a higher Technology Readiness Level (TRL) through validation testing, and working with Aerojet Rocketdyne and the company’s DoD partners. This maturation beyond the Phase II level intends to focus on computational predictive modeling of additive manufactured parts in order to meet the Air Force’s needs in process development, vendor qualification/process control, and airworthiness certification.

“We feel that VEXTEC’s VPS-MICRO: additive manufacturing software can be an integral tool in this effort because it represents the integration of additive manufacturing process modeling with performance prediction to provide a better tool for certification. Having Aerojet Rocketdyne’s keen interest will assure the process will interface with the commercial engineering practice,” noted Dr. Bob Tryon, VEXTEC’s President and CTO.
