Abstract
A strict mathematical approach is proposed to calculate the wave field of the ultrasonic beam used to test arising defects in the stone or brick masonry structures. The problem is reduced to a certain integral equation with respect to the distribution of the contact stress over the base of the US probe, in frames of the dynamic elasticity theory. There is given a comparison of the so-constructed solution with some approximate theories, including a scalar model. Finally, it is evaluated the possibility to use the US beams of the calculated geometry to detect defects in the masonry structures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
