Answer» The correct ANSWER is (b) False Best explanation: Acoustic emission testing method, in which SOLID materials EMIT sound or acoustic emission when they are stressed MECHANICALLY or thermally to the point where deformation or fracturing occurs. This creates ELASTIC waves which can be analyzed by an acoustic emission test system to monitor the condition of the material or casting under stress.
