Summary: This paper proposes a novel Bayesian updating framework based on principal component analysis (PCA) to solve the challenging problem of updating dynamic systems with high-dimensional output. The framework constructs a new likelihood function based on low-dimensional output principal components (PCs), which has been analytically proven to provide equivalent likelihood measures to the original one. An efficient Bayesian updating algorithm is also proposed in the PCA-based framework, which incorporates adaptive Bayesian updating with structural reliability methods (aBUS) and the Kriging model. Four examples are conducted to validate the proposed method.

Summary: An accurate dynamic model of the sluice is important for structural health monitoring and performance evaluation; however, it is difficult to fully capture the mechanical characteristics of the sluice due to parameter uncertainty. A novel methodology for updating the dynamic model parameters of a sluice is proposed, which combines an improved stochastic subspace identification method, a Kriging surrogate model, and the whale optimization algorithm. A case study using a physical model of a sluice demonstrates the feasibility and reliability of the proposed method, providing a foundation for structural health diagnosis of sluices.

Summary: This study introduces the dynamic condensation approach to improve the computational efficiency of response-based finite element model updating for large-scale structures. By selecting a small number of master DOFs and using a transformation matrix, the global vibration equation is reduced to enhance efficiency. Response and response sensitivities can be calculated directly from the reduced vibration equation, ensuring an efficient model updating process.

Summary: Electrorheological (ER) fluid is an intelligent material consisting of polarized micro- and/or nanoparticles dispersed into insulating oil. Recently, the incorporation of molybdenum disulfide (MoS2), a popular 2D material, has offered a new approach to develop high-performance ER materials. However, MoS2 ER material suffers from low polarization strength and high electrical conductivity. To overcome these limitations, a two-step method is used to prepare PANI and MoS2 hybrid composite nanoparticles with unique morphology. The optimized ratio of PANI to MoS2 is found to be 4:1, resulting in excellent material performance with shear stresses reaching 150 Pa. Overall, this material demonstrates great potential as an electrorheological material.

Summary: One challenge in intelligent fault diagnosis is the need for numerous labeled training datasets for satisfactory performance of the diagnosis model. Generating training data using a virtual model is a potential solution, and constructing a high-fidelity virtual model is crucial for data generation. This study proposes a digital twin-assisted dynamic model updating method to improve the fidelity and reliability of a virtual model, enhancing the quality of generated data. The method involves establishing a virtual model mirroring the vibration response of a physical entity, validating the modeling method through frequency analysis, and dynamically updating the virtual model using a physical-virtual signal interaction method.

Summary: A modified version of the Mode Shape-Based Estimation (MSBE) technique is proposed in this study to estimate the structural response at non-instrumented floors of a multi-story building. The proposed approach requires less user interference and provides improved accuracy, particularly for high-rise structures. The structure is modeled as a cantilever beam and the unknown terms of the frequency-dependent solution to the differential equation are estimated using the first natural frequency. Theoretical solutions are used to approximate deflected shapes at any frequency and the contribution of different beam modes is calculated to simulate the response at each time step, considering both low- and high-frequency content of the vibration and possible nonlinear behavior of the structure.

Summary: Recent studies have shown that metaconcrete made of engineered aggregates can reduce stress wave propagation induced by impulsive load. The energy from impulsive load can be absorbed by the engineered aggregates due to local vibration. Previous studies focused on 1D metaconcrete bar structures, while this study investigates the performance of 3D beam structures made of different types of metaconcrete under impulsive loading. The enhanced metaconcrete (EMC) beam shows better resistance to compressive, spalling, flexural, and flexural-shear damage compared to normal concrete (NC) and normal metaconcrete (NMC) beams.

Summary: This research proposes a new paradigm for designing intrinsically adhesive networks for injectable and photo-curable hydrogels, which not only provide strong adhesive contact, but also have a wide range of physicochemical properties. These adhesive networks are based on a family of polymeric backbones, where chains are modified to be intrinsically adhesive to host tissue while forming a hydrogel network through a hybrid cross-linking mechanism. Adhesion is achieved through a controlled synergy between interfacial chemistry and bulk mechanical properties.

Summary: This study focused on cartilage self-heating and investigated the impact of its coupling with mechanical stimuli on cell behavior. The findings suggest that the co-existence of thermo-mechanical cues has a superior effect on chondrogenic gene expression compared to either signal alone, with the TRPV4 channel identified as a key mediator of the thermo-mechanotransduction process.

Summary: Articular cartilage is a mechanically sensitive tissue where chondrocytes perceive and react to physical cues. This study explores the role of temperature as a regulatory signal for chondrocyte function and evaluates the effects of thermal and/or mechanical stimulation on chondrocytes in different types of scaffolds. The results suggest that the combination of dynamic thermal and mechanical stimuli has superior effects on chondrogenic genes and proteoglycan accumulation.

Summary: This paper investigates the nonlinear and nonlocal thermo-elastic behavior of a micro-tube reinforced by Functionally Distributed Carbon Nanotubes. The study includes the presence of internal and external piezoelectric layers, nonlinear viscoelastic-Hetenyi foundation, and axial fluid flow inside the microtube. The analysis involves deriving governing equations, converting them to time-dependent ordinary equations, and solving for the microtube's lateral displacements. The effect of different parameters on the nonlinear behavior of the system under parametric resonance condition is also investigated.

Summary: A domain-boundary element method based on modified couple stress theory is developed for transient dynamic analysis of functionally graded micro-beams. The method converts governing partial differential equations of motion into a set of coupled integral equations, which are then solved using the Houbolt time marching scheme. Numerical results show that metal-rich micro-beams and those with a smaller length scale parameter ratio exhibit higher displacements and larger normal stresses.

Summary: This article presents a multifield asymptotic homogenization scheme for analyzing Bloch wave propagation in non-standard thermoelastic periodic materials. The proposed method derives microscale field equations, solves recursive differential problems within the unit cell, establishes a down-scaling relation, and obtains average field equations. The effectiveness of this approach is validated by comparing dispersion curves with those from the Floquet-Bloch theory.

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.
