Nonlinear ultrasonic evaluation of load effects on discontinuities in concrete

Antonaci, P. / Bruno, C.L.E. / Bocca, P.G. / Scalerandi, M. / Gliozzi, A.S.

AbstractThe presence of discontinuity surfaces in concrete structures, i.e. two or more layers in contact, may be an existing situation with evident relapses on damage formation and progression. Differences occur depending on the type of discontinuity, which could be a thin weaker layer or a pre-existing crack. The behavior of pre-existing interfaces is here studied by means of the Scaling Subtraction Method, a Nonlinear Ultrasonic Non-Destructive Technique, that revealed to be effective in describing the mechanical evolution of concrete samples with discontinuity surfaces under the effects of compressive loads.
