Newswise — FAYETTEVILLE, Ark. – Ashok Saxena, Distinguished Professor and dean of the College of Engineering at the University of Arkansas, is available to comment on cracks and metal damage to airplane fuselages. Saxena’s research has focused on metal fatigue of aircraft materials and creep-fatigue interactions, which cause degradation in structural metals and may lead to sudden and catastrophic failure of critical parts.
His research group developed laboratory test methods for understanding the creep-fatigue phenomenon. Their work resulted in mathematical models for describing the kinetics of creep-fatigue damage progression in metals and algorithms for predicting the rate of damage accumulation in high temperature components.
The American Society for Testing and Materials (ASTM International), the premier international organization for test standards of materials, issued two standards, one in 1992 and another in 2010, that were significantly based on the work of Saxena’s research team over the past 20 years.
