Modeling of ultrasonic measurement systems with waveguides

Abstract

The ultrasonic pulse-echo technique is used for non-intrusive process monitoring. The material properties must be investigated in very complicated conditions - high temperature and others. The special high temperature transducers or waveguides must be used to protect the transducer from the high temperature of the material. Objective of this work was comparison of the two modeling techniques of the ultrasonic waveguides for application of the ultrasonic measurements: 1D matrix technique and 2D finite element method.
