Acoustic Harmonic Generation Measurements for Materials Characterization
In the first presentation of the Otto Buck memorial session, Dr. Donald Thompson described contributions of Dr. Otto Buck on the theories of finite amplitude waves and elastic constants and his experimental work involving reflections from stress free interfaces and harmonic generation. The speakers following Dr. Thompson described many more of Dr. Buck’s contributions in a wide variety of topics. Listening to the sessions speakers talk of their work with Otto made this author realize just how wide Otto’s interests and expertise were. Here, we come full circle and discussed the preliminary results of work which relates directly to contributions remembered by Dr. Thompson regarding harmonic generation. This work was initiated by Dr. Buck at the Ames Laboratory and continues there.
