AbstractAbstract
[en] The velocities of ultrasonic waves in a uniaxially compressed concrete are influenced by microcracking. The experimental results are commented and a model of propagation in a randomly microcracked medium is built. The model shows a high anisotropy of propagation when all cracks have the same orientation

Les celerites de propagation d'ondes ultrasonores dans une eprouvette de beton soumise a des cycles de compression simple sont reliees a son etat de microfissuration. On presente les resultats experimentaux et on construit un modele theorique de propagation en milieu fissure aleatoirement. On montre en particulier la forte anisotropie induite par une orientation preferentielle des fissuresOriginal Title
