A semianalytical solution alternative and complementary to modal technique is presented to predict and interpret the ultrasonic pulsed-bounded-beam propagation in a solid cylinder embedded in a solid matrix. The spectral response to an inside axisymmetric velocity source of longitudinal and transversal cylindrical waves is derived from Debye series(More)
In order to use nondestructive techniques (NDT) for the survey of reinforced concrete structures, it is important to show that they are able to measure the cover concrete characteristics related to its durability. For this purpose, various NDT were implemented to evaluate the mechanical and physical properties of concretes whose porosity is ranging from(More)
