19003 Ultrasound in Materials Science and Engineering (Ultrasound Experiment Set 3)

Ultrasound in Materials Science and Engineering (Ultrasound Experiment Set 3) Non-destructive testing (NDT) using the most common ultrasonic testing methods, such as pulse-echo and through-transmission methods, angle head testing and the TOFD method on various material samples One of the main applications of ultrasound is non-destructive testing (NDT). Here, ultrasound testing has established itself as a standard method for analyzing material defects such as cracks, cavities, gas bubbles and inhomogeneities in a wide variety of materials such as metals, plastics or composites. A variety of methods have been developed that can meet the individual testing tasks. With this experiment set, some of the most common test methods in ultrasonic testing, such as pulse-echo method, transmission method, angle head testing and the TOFD method, are explained and applied to various material samples. On the basis of knowledge of the physical properties of ultrasonic waves (e.g. speed of sound, sound a
