Large chemical and petroleum product storage tanks are prone to attack by corrosion, the material and the welds need to be inspected throughout their service life for signs of damage. Many independent robotic systems have been developed, but no one can accomplish an entire inspection task without the need to empty the tanks nor the required human walk(More)
In concrete, fatigue and freeze-thaw are associated with the progressive growth of internal microcracks. The Ultrasonic Pulse Velocity (UPV) technique, one of the most widely used Nondestructive Testing (NDT) methods, is promising in evaluating internal microcracks and eventually detecting damage. The primary objective of this research was to determine the(More)
