“…Such a unique nonlinear feature allows the early detection of incipient fatigue damage in structures. Superharmonics is a classical nonlinear ultrasonic phenomenon which has been widely reported using experiments in the literatures [27][28][29]. Again, the focus of this research is on developing an efficient numerical approach to model such a nonlinear effect.…”

This paper presents the local interaction simulation approach (LISA) for efficient modeling of linear and nonlinear ultrasonic guided wave active sensing of complex structures. Three major modeling challenges are considered: material anisotropy with damping effects, nonlinear interactions between guided waves and structural damage, as well as geometric complexity of waveguides. To demonstrate LISA's prowess in addressing such challenges, carefully designed numerical case studies are presented. First, guided wave propagation and attenuation in carbon fiber composite panels are simulated. The numerical results are compared with experimental measurements obtained from scanning laser Doppler vibrometry (SLDV) to illustrate LISA's capability in modeling damped wave propagation in anisotropic medium. Second, nonlinear interactions between guided waves and structural damage are modeled by integrating contact dynamics into the LISA formulations. Comparison with commercial finite element software reveals that LISA can accurately simulate nonlinear ultrasonics but with much higher efficiency. Finally, guided wave propagation in geometrically complex waveguides is studied. The numerical example of multimodal guided wave propagation in a rail track structure with a fatigue crack is presented, demonstrating LISA's versatility to model complex waveguides and arbitrary damage profiles. This paper serves as a comprehensive, systematic showcase of LISA's superb capability for efficient modeling of transient dynamic guided wave phenomena in structural health monitoring (SHM).

“…Figure 11 depicts the variation in the acoustic nonlinearity of AISI 316L stainless steel fatigue-failed specimens under various strain amplitudes. The acoustic nonlinearity increased with strain amplitude due to the occurrence of fatigue-driven plastic deformation, and is therefore closely related to the strain amplitude and to the accumulation of fatigue deformation [29]. To understand the microstructural features that influence the distortion of the acoustic wave and result in superharmonic generation, we refer to the previously shown and discussed microstructural evolution during fatigue damage.…”

Strain-induced phase transformation and damage accumulation in austenitic stainless steel subjected to cyclic loading were investigated by nondestructive evaluation. The cyclic loading test was performed at various strain amplitudes at the same strain rate. The volume fraction of the strain-induced phase transformation (α -martensite) was determined by ferrite scope and magnetic coercivity measurement. The damage accumulation and microstructure of cyclic loading specimens were characterized by microstructural observation. The cyclic hardening and cyclic softening behavior are discussed in terms of the generation of strain-induced martensite phases and a dislocation substructure at each strain amplitude. The volume fraction of the strain-induced phase increased with the strain amplitude. The increase in α -martensite was evaluated by measuring the ultrasonic nonlinearity parameter. The presence of α -martensite is sufficient to distort the austenitic matrix due to an interface misfit between the austenite matrix and α -martensite, resulting in wave distortion of the longitudinal wave. From this wave distortion, super-harmonics may be generated with nucleation of the strain-induced martensite, a process that strongly depends on the strain amplitude.

Abstract. This study presents a damage detection system using modulated ultrasonic and fiber Bragg grating (FBG) in Aluminum thin plate. In the system, modulated ultrasonic technology and FBG sensing technology were combined to detect damage. Piezoelectric patches used to excite ultrasonic and FBG were pasted on a Acrylic plate and then contacted with specimen by coupling, so the excitation point of ultrasonic and sensing point of FBG can be modified arbitrarily. Experiment results showed that the system can detect the damage signal more flexibly.
