In order to investigate fracture mechanisms in concrete, quantitative acoustic emission (AE) techniques can be applied. In this context a 3D localization of the recorded AE events is required. An eight channel acquisition unit was used to record AE parameters and waveforms. AE events, recorded during splitting tests, were analyzed quantitatively. With the help of a localization analysis and a relative moment tensor inversion analysis AE source characteristics could be recovered in relation to the stress state.
