Summary: Guided waves are becoming popular in the NDT industry due to their cost and time-saving potential in inspecting structures and high sensitivity in detecting micro-defects. This study uses experimental and numerical approaches to detect and locate cracks in isotropic plates using the second harmonic of the symmetric guided wave. The results show that the proposed technique is accurate, reliable, and does not require baseline data, providing an advantage over conventional ultrasonic testing techniques.

Summary: This study presents constitutive laws of structural members using granular micromechanics approach, deriving macroscopic behavior by investigating average behavior of grain-pair interactions. Closed-form solutions for constitutive relationship of uniform and functionally graded materials are derived, demonstrating versatility and computational efficiency of the proposed approach. Analyzing structural members made of particle-binder composites reveals interesting one-way and two-way coupling behavior between internal forces and moments that cannot be achieved through closed-form solutions.

Summary: This study investigates the nonlinear dynamics of a cracked plate undergoing large-amplitude vibration and explores the influence of structural damage on the nonlinear characteristics of the plate. Various parameters affecting the nonlinear response, such as crack stage, aspect ratio, and excitation location, are discussed. Results show that the presence of a crack makes the plate more fragile, especially when the crack is parallel to the long side of the plate.

Summary: In this paper, a method for accurately detecting closed cracks using nonlinear Lamb waves with phase-velocity mismatching is proposed, which excludes the intrinsic material nonlinearity. Simulations and experimental studies were conducted to analyze the double frequency Lamb waves induced by the closed cracks and the intrinsic material nonlinearity. The results show that the double frequency Lamb waves induced by material nonlinearity are negligible compared to those caused by the contact acoustic nonlinearity of the closed cracks. The proposed method can accurately detect closed cracks, and the acoustic nonlinearity parameter increases monotonically with crack evolution. The findings of this study provide a feasible method for the detection and characterization of closed cracks.

Summary: This study proposes a new method to quantitatively evaluate the severity of near-boundary crack damage by utilizing the reflection coefficient of waves. Analytical derivations show that the amplitude of evanescent waves is negatively correlated with the damage severity, making it possible to use the amplitude ratio as a damage indicator. Through an inverse algorithm, estimated amplitude ratios can be compared with theoretical values to determine the severity of the damage. The results verify the potential value of this indicator in the health monitoring of slender beam structures.

Summary: This paper presents a study on the fatigue damage of deep beams in bridges and other critical infrastructure. Through large-scale fatigue tests and crack measurements, it is found that fatigue is mainly associated with the degradation of aggregate interlock and progressive damage in critical loading zones. It is also observed that reducing the maximum load can increase the fatigue life and switch the failure mode from shear to flexure.

Summary: This paper demonstrates the application of Vibro-Acoustic Modulation measurement for damage detection in notched carbon fibre reinforced polymers (CFRP). An ultrasonic signal is introduced into the specimen through a piezoceramic actuator, which is modulated by a low-frequency vibration. Open hole tensile specimens made from a quasi-isotropic CFRP layup are tested, and degradation in the form of matrix cracks or delaminations can be detected as a modulation increase. The presented method can be used for damage monitoring in CFRP.

Summary: This paper presents two distinct model updating strategies for dynamical systems with local nonlinearities based on acceleration time history responses measured spatially across the structure, one involving the decoupling of linear and nonlinear characteristics, and the other updating linear and nonlinear parameters simultaneously. By solving numerically simulated examples and experimenting with benchmark data, the effectiveness of the strategies and their capability in damage identification in nonlinear systems were evaluated.

Summary: In this study, multiple collisions of granules on a substrate are analyzed using Collisional Smooth Particle Hydrodynamics (CSPH) to understand the influence of impact-induced deformation on subsequent collision dynamics. It is found that the collision dynamics are dependent on the impact location and the deformation caused by preceding impacts. The accuracy of three theoretical models is also evaluated by comparing their predictions with CSPH results, and it is discovered that these models are only useful for predicting collisions at the same location repeatedly.

Summary: This paper investigates anisotropic elastic, magnetoelectroelastic, and quasicrystal solids and presents their equations of time-harmonic motion and constitutive relations in a compact and unified form. A matrix approach is proposed to derive the 3D time-harmonic Green's functions for these materials. The effects of phason field dynamics on the phonon oscillations in quasicrystals are studied in detail. The paper provides a strict proof that the eigenvalues of the time-harmonic magnetoelectroelaticity problem are all positive. It also demonstrates the application of the obtained time-harmonic Green's functions in solving boundary value problems for these materials using the derived boundary integral equations.

Summary: This paper investigates the peeling behavior of a viscoelastic film bonded to a rigid substrate and establishes a theoretical peeling model. The study reveals three typical relationships between the peeling force and peeling velocity, which depend on the viscous dissipation within the film and the rate-dependent adhesion at the interface. Additionally, factors such as film thickness, interfacial toughness, and interfacial strength are identified as influencing the steady-state peeling force.
