Abstract
A fnite diference algorithm that evaluates the health conditions of a bonded joint is presented and discussed. Te mathematical formulation of the problem is developed, paying particular attention to the singularity around the corners of the joint and implementing an original discretisation method of the partial diferential equations governing the propagation of the elastic waves. Te equations are solved under the only hypothesis of a bidimensional feld. Te algorithm is sensible to defects in the bonded joint and can be used as an efective structural health monitoring tool, as proven by the experiments that show close agreement with the numerical simulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
