Abstract

The determination of elastic constants by using time-resolved line-focus acoustic microscopy (TR.LFAM) is discussed. Waveforms have been measured with a time-resolved line-focus acoustic microscopy system. A measurement model which simulates the measurements is also introduced for parametric studies of the waveforms. The determination of elastic constants is achieved by systematically comparing the relative wave-mode time-delays obtained from the measurement model and the experiments. The method has been applied to determine elastic constants of both isotropic and anisotropic materials.
