Summary: This paper investigates the non-linear vibration characteristics of an all-composite sandwich (ACS) plate with a hexagon honeycomb core (HHC). Through vibration tests on the HHC-ACS plate specimens, it is observed that the natural frequencies of the plate display an inversed downward trend with increasing excitation amplitude due to the material nonlinearity of the honeycomb core. A nonlinear theoretical model based on Reddy's third-order shear deformation theory is developed, and the effects of material and geometric parameters of HHC on the amplitude-dependent vibration behavior are investigated.

Summary: 3-D braided composite three-way circular tubes are seamless connected tubes used for high strength connecting joints. A novel braiding method of 'yarn-added, yarn realigned' was developed to prepare three-way tubular preforms. Low-velocity impact compressions (LVIC) were conducted to study the impact damage effect of branch length and braiding layers. The test results showed that the ultimate strength was positively correlated with the impact energy and braiding layers, while negatively correlated with the branch tube length. The influence of braiding layers on the LVIC behaviors is more significant than that of the branch length.

Summary: By conducting monotonic tensile and fatigue tests of SiC/SiC composites at 1300 degrees C, it was found that the fatigue behaviors can be divided into three zones. In all three zones, inelastic strains accumulation and stiffness reduction were observed due to matrix cracking, interface damage, and failure of fibers. The fatigue life is long in the run-out zone when the maximum stress is lower than the proportional limit stress (PLS). In the stress-insensitive zone, fracture depends on high-temperature and oxidation effects. Failure in the stress-sensitive zone is dominated by the fiber strength. The interface behaviors greatly affect the fatigue life above the PLS.

Summary: This paper proposes a meta-plate structure with periodic tunable-stiffness nonlinear oscillators (NLOs) for nonlinear vibration and flutter suppression. The NLOs can be adjusted to achieve tunable nonlinear stiffness, providing a tunable-bandgap characteristic that effectively attenuates low-frequency broadband vibration. The study demonstrates that by properly adjusting the NLO parameters, such as spring stiffness, pre-compression/-tension ratio, and mass ratio, the meta-plate can achieve broadband energy transmission and nonlinear responses, including chaotic motion with extremely small amplitude. The findings suggest that the tunable-stiffness-NLOs-based metamaterial design offers a novel and effective approach for nonlinear vibration and flutter suppression of supersonic plates.

Summary: The paper investigates the nonlinear vibration of a two-layer beam under thermal and mechanical loadings. The model is based on the extended Timoshenko beam theory considering geometric nonlinearities. The obtained resonance curves show a hardening phenomenon and instability zones under large vibrations.

Summary: This work investigates the vibration and aeroelastic stability behavior of honeycomb core sandwich panels with four-side simply supported boundaries in supersonic airflow. The results show that the hexagonal honeycomb core can improve the natural frequencies of the panel. The honeycomb core thickness has a major influence on the critical dynamic pressure of the honeycomb sandwich panel, and the cell thickness, the cell angle and internal aspect ratio have no significant effect on the critical dynamic pressure. Compared with the basic isotropic panel, the mass can be reduced by nearly 70% using the honeycomb panel in the condition of the same critical dynamic pressure, which is of great significance to reduce the weight of the aircraft panel.

Summary: The cyclic stress from rapidly alternate heating and cooling, as well as strong noise, can significantly impair the combustion chamber of an aero-engineer, leading to reduced fatigue performance. Through high temperature and strongly acoustic response tests, along with fatigue tests under various conditions, a fatigue life model was developed, and simulation was used to validate the prediction results against tests. The simulation showed that higher temperatures and rapidly alternate heating and cooling loads expanded the nonlinear response of the structure, aggravating vibration behavior and reducing fatigue life.

Summary: This paper investigates the fatigue behaviors of polysilicon using molecular dynamics simulations, finding that factors such as fatigue loading, grain number, and temperature significantly affect the fatigue behaviors. Damage accumulation in polysilicon can be described by a conventional damage evolution equation, which is used to construct a continuum mechanical model for studying the impact of fatigue on electrically actuated microbeams. Theoretical results show that fatigue can induce dynamic pull-in failure in microbeams, emphasizing the importance of carefully selecting driving voltage in the design and application of MEMS resonators.

Summary: The nonlinear micromechanical finite element model is used to analyze the steady-state time-dependent deflections of weakly connected layered composite panels, considering different displacement theories and environmental effects. Various techniques are employed to predict deflection parameters under steady-state loadings, and the model responses are compared with published data to capture actual structural distortion.

Summary: This paper proposes an analytical model for fiber reinforced polymer composite cylindrical shells (FRPCCSs) considering material and geometric nonlinearities and thermal effects, which can predict natural frequencies, damping ratios, and resonant responses. Experimental validation shows that the natural frequencies of composite shell specimens initially decrease and then increase with increasing excitation amplitude, while damping ratios and resonant responses of FRPCCSs increase with excitation amplitude and environmental temperature. The study also highlights the significant effect of environmental temperature on the damping performance of FRPCCSs.
