Ultrasonic inspection is accomplished by using electronically controlled pulses introduced into a material from an outer surface. Then, the ultrasonic energy travels within the material, finally reaching again an outer boundary. Material condition is diagnosed from characteristics of the receive ultrasonic energy. The technique of using ultrasonic pulse echo to investigate and examinate the thickness of curved multilayered structures will be presented in this thesis. It also studied physics conditions which the curvatures of multilayered polymer systems might effect thickness measurements. The real location of the focus of an acoustic beam in curved layered structures was calculated by a ray-optical model. Experimental results using the ultrasonic pulse-echo measurement system are presented. The optimization of the focal distance is discussed.Dept. of Industrial and Manufacturing Systems Engineering.
