“Through the use of StressCheck® the A-10 Aircraft Structural Integrity Program’s (ASIP) Analysis Group is able to model more accurately the physics of fatigue crack propagation in critical aircraft structure. Through this tool we are able to model, analyze and predict failure of aircraft structure and then develop crucial inspection and maintenance planes to ensure the safety and sustainability of our nations warplanes. Without the analysis capability provided to us through StressCheck® we would not be able to provide accurate assessments of the A-10 structure to top USAF leadership.”
