Abstract

Finite element analysis is a well established technique for studying ultrasonic wave propagation in NDE applications. In particular, finite element analysis allows variations in specimen geometry and transducer configurations to be studied without the cost of manufacturing a large number of physical prototypes. In this research, several transducer and creep specimen configurations were investigated to determine how well each setup performed for in-situ monitoring. Preliminary results show that pulse-echo measurements with a remote magnetostrictive transducer and through-transmission measurements with high temperature piezoelectric transducers each have specific advantages. Experimental validation was also performed.
