What if there is strong vibration, shock or acceleration in the material?

We have demonstrated measurement on Navy guns that undergo severe shock during firing. Generally, the frequency and method of measurement isolate acoustic shock and vibration effects. Elastic behavior is material dependent and more elastic materials can have an influence on the measurement as the propagation path of the ultrasound changes due to shape changes in the material. In some cases, these effects can be compensated for. In other cases, the magnitude of these effects is very small relative to the change due to temperature. Overall, vibration, shock and acceleration have application specific effects, but do not preclude ultrasonic measurement and will not destroy or disrupt ultrasonic sensors.
