Using state-of-the-art physics-based models, Veracity’s scientists in Brigham City, UT, are building an innovative approach to reducing uncertainties in modeling propellant mechanical properties used to determine motor service lives. The goal is to reduce uncertainty by a minimum of 10 percent, resulting in higher confidence in the reliability of Solid Rocket Motor (SRM) weapons systems. In addition to integrating the models into a software framework, Veracity will illustrate the benefits of using the toolset on a deployed SRM system.
This project supports the Air Force Research Lab (AFRL), Rocket Propulsion Division, Edwards AFB.
Aging and Surveillance
At Veracity we employ state-of-the-art analysis tools for aging and surveillance (A&S) of energetic materials. We support our customers throughout the A&S life cycle:
- failure mode and effects analysis (FMEA)
- test plan generation
- data processing
- chemical evolution modeling
- safe-life and service-life calculations
- reliability modeling
At each phase we work closely with material experts and engineers to ensure current scientific understanding and product familiarity.
We create advanced material models for energetic materials. Our experience includes creating models for polymeric binders, particulate reinforcement, and particulate agglomeration. We provide greatest value by quickly prototyping and verifying material models and then implementing them in production-ready code. At Veracity, we build models using Python, C++, and various other programming languages. We also have built models for integration into third- party analysis tools, such as user-defined mechanical behavior subroutines (UMAT) for Abaqus (finite element analysis tool).
