We present a simple mathematical model in one dimension for structural health monitoring of a single lap joint. In the model, we simulate a vibrational signal which propagates throughout three subdomains: from a first aluminum panel to a second one, connected by an adhesive layer. In particular, modeling a joint area between the two layers, we easily reproduce the presence of a damage (debonding) as a simple disconnection between the first aluminum plate and the adhesive layer. To validate the mathematical model, an analytical/numerical/experimental correlation is presented. We develop (and make available) a MATLAB program (by means of finite differences discretization), with a brief user manual, which simulates the discussed problem.

Abstract
We present a simple mathematical model in one dimension for structural health monitoring of a single lap joint. In the model, we simulate a vibrational signal which propagates throughout three subdomains: from a first aluminum panel to a second one, connected by an adhesive layer. In particular, modeling a joint area between the two layers, we easily reproduce the presence of a damage (debonding) as a simple disconnection between the first aluminum plate and the adhesive layer. To validate the mathematical model, an analytical/numerical/experimental correlation is presented. We develop (and make available) a MATLAB program (by means of finite differences discretization), with a brief user manual, which simulates the discussed problem.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
