متن کاملImpact of Applied Loads on Guided Wave Structural Health Monitoring
Guided wave structural health monitoring is a challenging problem, in part because of the complexity of signals received in a real structure containing geometrical features and boundaries. Signals scattered from damage can be one or two orders of magnitude smaller in amplitude than the direct arrival. Detection of these small, scattered signals is often accomplished by comparing signals of inte...
متن کاملNonlinear Ultrasonic Waves for Structural Health Monitoring
Nonlinear ultrasonic waves in solids have shown good sensitivity to quasi-static stresses. The stress sensitivity of elastic waves is typically associated to finite strains (e.g. theory of acoustoelasticity). In the case of waveguides, classical nonlinear theories for guided waves are still based on the assumption of finite strains. In the case of constrained solids subjected to thermal excursi...
متن کاملPiezoelectric Wafer Active Sensors for Structural Health Monitoring of Composite Structures Using Tuned Guided Waves
Piezoelectric wafer active sensors (PWAS) are lightweight and inexpensive transducers that enable a large class of structural health monitoring (SHM) applications such as: (a) embedded guided wave ultrasonics, i.e., pitch-catch, pulse-echo, phased arrays; (b) highfrequency modal sensing, i.e., the electro-mechanical (E=M) impedance method; and (c) passive detection (acoustic emission and impact...
متن کاملGuided Waves monitoring
Lo screening di tubazioni utilizzando il metodo ad onde guidate è una realtá assodata sia in Italia che nel resto del mondo. I metodi PND tradizionali sono metodi per il controllo di punti o di aree ad estensione limitata. Inoltre il target della ispezione diventa di anno in anno più complesso a causa dell’invecchiamento delle strutture e delle carenze tecniche di alcuni metodi PND classici, ev...
