Summary: The main aim of this study is to extend the isogeometric analysis (IGA) based on higher-order shear deformation theory (HSDT) with Soldatos's continuous function f(z) to investigate the free vibration characteristics of bio-inspired helicoid laminated composite (BiHLC) plates on an elastic foundation.

Summary: This paper presents an alternative strategy for simultaneous predictions of severity and location parameters of delamination in composite plates using a combination of random forests (RF) and natural frequency-shift damage assessment methods. The study includes the establishment of a robust finite element (FE) procedure, validation of the FE procedure, and development of four RF models with different architectures. Results show that the proposed RF-based method is capable of accurately predicting five parameters quantifying the location and severity of delamination in composite plates, with a coefficient of correlation as high as 0.996 and up to 90% accuracy for classifying the delaminated interface.

Summary: Ultrasonic guided waves provide a convenient and practical approach to structural health monitoring and non-destructive evaluation, with dispersion curves describing the relationship between frequency and propagation characteristics. Accurate dispersion curve information is valuable in many guided wave-based strategies, and can be determined through experimental observations and a system identification procedure. This study uses a scanning-laser Doppler vibrometer to record Lamb wave propagation in a composite plate and performs a Bayesian analysis using the Markov-Chain Monte Carlo method to determine dispersion curve information and infer confidence in the predicted parameters. The probabilistic approach is shown to have advantages over traditional estimation methods.

Summary: This paper investigates the vibration characteristics of foam-filled fiber composite Beetle Elytron Plate (BEP) using the finite element method. The study explores the influence of structural parameters, such as length-to-width ratio, core height-to-thickness ratio, skin thickness, and foam density, on the natural frequency and mode. The results show that the length-to-width ratio, core height-to-thickness ratio, foam density, and skin thickness have varying effects on the first and second order frequencies of the BEP. The findings provide references and suggestions for the design and application of sandwich structures, advancing the research on the mechanical properties of BEPs and establishing a foundation for their engineering practices.

Summary: This study presents a finite element method using a 9-node isoparametric plate bending element, considering transverse shear effects based on the first-order shear deformation theory, for the free vibration analysis of rectangular cut-out plates on an elastic foundation. The formulation accounts for parabolic strain variation and includes the effect of rotary inertia. Comparison with established results shows a maximum variation of 2.24% without rotary inertia and 0.02% with rotary inertia. Validation of cut-out plates using the finite element method shows a maximum variation of 1.3% with established results. The effects of increasing cut-out dimensions, different layouts of cut-outs, aspect ratios, and thickness-to-side ratios on the free vibration response of plates on an elastic foundation are investigated.

Summary: The study investigates mechanical buckling of graphene reinforced composite laminated plates under different load conditions and boundary conditions, considering the temperature dependence and anisotropy of the material properties. The critical buckling load is influenced by parameters such as elastic foundation, temperature, layup scheme, and graphene distribution pattern. Elastic foundation has a smaller impact on critical shear buckling load compared to uniaxial and biaxial mechanical loads, with the highest load observed in the [0](10) layup scheme.

Summary: This paper proposes a novel triple-gradient phononic acoustic black hole (ABH) beam that strategically manipulates multiple gradients to enhance its performance. The study reveals that the ABH effect is not solely brought about by the thickness gradient, but also extends to the power-law gradients in density and modulus. The synergistic development of three different gradient effects leads to more pronounced and broader bandgaps in PCs.

Summary: This study numerically investigates the behavior of an ultrasonically driven gas bubble between two parallel rigid circular walls with a cylindrical micro-indentation in one wall. The primary objective is to determine the conditions that facilitate the removal of particulate contamination from the indentation using the bubble jet. The study found that the bubble jet can effectively remove contamination from the indentation for certain ranges of indentation diameter, but becomes less effective for larger indentation diameters.
