Such a technique might be a viable tool in nondestructive evaluation. This contribution firstly outlines the elements of a hitherto lacking three-dimensional theory of thermoelastic sound generation and secondly a comparison with experimental results is given.enexperimentkurze Laserpulsequantitatives theoretisches ModellThermoelastischer EffektUltraschallerzeugungWinkelcharakteristikzeitlicher Signalverlauf620658670conference paper
