Clarkson's Minnetyan Honored By NASA For Work On
Levon Minnetyan (minn-ET-tyon) of Canton, associate professor of Civil and Environmental Engineering at Clarkson University, was recently honored for his contribution to the creation of the National Aeronautics and Space Administration's award-winning GENOA/PFA (Progressive Failure Analysis) software.
Dr. Christos C. Chamis, senior aerospace scientist in the Research and Technology Directorate at NASA Lewis Research Center in Cleveland presented a Certificate of Recognition to Minnetyan prior to a symposium by Chamis held at Clarkson recently.
Minnetyan was part of a team that earned Software of the Year honors for their design of GENOA/PFA, which can predict the durability and damage tolerance of structures made from metals, composites and reinforced concrete, thereby reducing the number of tests needed for development, qualification and certification of aerospace structures.
His involvement with composite structures began in 1988 during a summer faculty fellowship at the Lewis Research Center. Over the next 12 years, computational simulation methods were developed at Clarkson to evaluate the progressive fracture and damage tolerance of fiber composite structures.
Honeywell Corporation is using the woven composite simulation methods to design low-cost high-temperature ceramic matrix composite engine combustion chambers.
Minnetyan developed methods for the evaluation of built-up composite structures, pressure vessels, and 3-D reinforced woven/braided fiber composites. He also augmented the capabilities by adding simulation of a new cost-effective manufacturing method using composite preforms, static and dynamic cyclic fatigue evaluation, fatigue under random vibration loading, and impact response.
Computational methods developed by Minnetyan were integrated with a specialized graphical user interface (GUI) developed by AlphaStar Corporation, a software company.
Users of the GENOA/PFA software package also include the U.S. Air Force, Boeing, Honeywell and General Electric Aircraft Engines.
