In this work, a code of finite element method is developed for numerical simulation of the acoustoelastic effect in pre-stressed media. The possibility of assessing the stress status, by using the EMAT (electromagnetic acoustic transducer) receiver for precise measurement of LCR (refracted longitudinal) wave, is investigated. Besides that, the relationship between the polarization of transient Rayleigh wave and the state of stress is also predicted by simulation.
