Abstract: Propagation of nonlinear waves in solid waveguides is a branch of wave mechanics that has received ever-increasing interest in the last few decades. Nonlinear guided waves are promising candidates for interrogating long ...

Abstract: This paper presents a global-local (GL) method to simulate the interaction of ultrasonic guided waves with structural defects in isotropic and multilayered composite platelike structures. The GL method uses a full ...

Abstract: This paper casts pipe inspection by ultrasonic guided waves in a feature extraction and automatic classification framework. The specific defect under investigation is a small notch cut in an ...

Abstract: Health monitoring of steel strands is the subject of much research in the nondestructive evaluation and civil engineering communities. This paper deals with a guided stress wave method for stress monitoring and defect ...

Abstract: The nondestructive characterization of the material properties and the detection of hidden discontinuities in a highly porous, open cell, carbon foam using ultrasonics are presented. The propagation of ultrasonic waves in ...

Abstract: The use of adhesively bonded carbon fiber reinforced polymer (CFRP) laminates is increasingly being considered for the rehabilitation of metallic structures. The effective structural monitoring of steel/CFRP adhesive joints ...

Abstract: This paper presents a technique developed on the basis of ultrasonic guided waves to monitor prestress levels in multiwire prestressing strands. The transducer layout identified for stress measurement is composed of an ...
