Mr. Andrews most recently served as head of the Structural Integrity division, where he managed the research activities of over 50 engineers, scientists, and technicians conducting experimental and analytical research related to characterizing, controlling, and predicting damage in materials and structures. These investigations deal with a broad range of damage, including that caused by fatigue, corrosion, and other complex failure mechanisms. He was the program manager on UDRI contracts that address the development and application of structural integrity technologies for damaged and aging structures of many types of materials. He has over 35 years of experience conducting and directing materials-related research efforts.
Research activities conducted within the Structural Integrity division include: (a) performing durability and damage tolerant assessments (DADTA) of structures, (b) evaluating the reliability of nondestructive evaluation (NDE) systems, (c) developing advanced NDE technology and systems, (d) creating technology for conducting DADTA studies on aircraft and subsystems, (e) developing the CRACKS life prediction software system, and (f) developing risk analysis methodologies for structural maintenance planning, and (g) analysis of loads and usage data from commercial transport aircraft.
Mr. Andrews has developed advanced ultrasonic techniques for imaging damage in composite materials and detecting corrosion in metallic structures. He has also developed a health monitoring system for assessing in-service damage in composite structures and engineered optical instrumentation and techniques for robot vision and real-time inspection. He has experience in the fabrication and testing of advanced materials including structural composites, plastics, elastomers, and adhesive bonded joints.
