The proposed instrumentation using the combined ultrasonic attenuation and speckle image correlation strain measurement techniques addresses these problems by providing a compact, rapid and robust nondestructive examination system for evaluating the material macroscopic properties and surface crack-opening displacements at critical locations on the full scale operating structures. Extension of the fundamental correlation between analytical ultrasonic nondestructive evaluation and mechanical performance, evaluation of a rugged ultrasonic attenuation measurement system, integration of speckle correlation-based strain sensing device.
