Strength and stiffness of masonry brick and mortar have been selected to better reproduce the poor mechanical properties of the materials commonly used in the real historical bridges construction.
The mechanical properties of the materials were derived from some characterisation tests carried out on mortar and masonry samples collected during the bridge construction.
Crack advancement, in fact, is accompanied by the emission of elastic waves, which propagate within the bulk of the material.
