“…In our work, a buckling model of the ECCSS is established theoretically based on the interlayer stress continuous theory, rather than the segmented displacement theory. The theory in this paper is different from literature [39] in the model construction method. Under the premise of satisfying the computational accuracy, the control equations derived in this paper have fewer unknown variables, and the analytical theory has higher computational efficiency.…”

The research aims at exploring the buckling behavior of embedded co-cured composite sandwich structure (ECCSS) under static load. In accordance with the research objective, an analytical model, which is based on the interlayer stress continuous theory to formulate governing differential equations for predicting the critical buckling loads of ECCSS, has been established. The theoretical solution that satisfies the boundary conditions is obtained using the principle of minimum potential energy. The results obtained by ANSYS software have been used to corroborate the correctness of the analytical model. In addition, effects of various structural parameters (such as ply angles and skin-to-core thickness ratio) on buckling behavior of ECCSS have been investigated.

Multi-phase functionally graded carbon nanotube-reinforced composite damping structure (FG-CNTRCDS) excels other composite structures in that it inherits the excellent performance of the functionally graded carbon nanotube-reinforced composite, and exhibits an improved damping performance due to the added viscoelastic damping films. Despite its superior properties, investigations on dynamic properties of the FG-CNTRCDS under clamped boundary conditions are still lacking. Aiming at filling this gap and paving the way to accurately design and analyze the FG-CNTRCDS, a dynamic analytical model, which is based on the higher-order shear deformation theory to formulate governing equations for predicting free vibration of FG-CNTRCDS, has been established. The analytical solution that satisfies clamped boundary conditions is obtained using the Rayleigh-Ritz method. The existing analytical results from the literature have been used to verify the correctness of the theoretical model. In addition, effects of various structural parameters (such as volume fraction and core-to-skin thickness ratio) on dynamic performance have been investigated. Here, the dynamic performance refers to the first-order natural frequency and the first-order loss factor.

This study investigates the effects of nanoclay (NC) particles on the buckling behavior of carbon/Kevlar intraply hybrid composites. The laminates containing various amounts of NC particles (0.5%, 1%, 1.5%, 2%, and 3% by weight) were manufactured using hand layup stacking followed by vacuum bag molding process. The prepared samples were subjected to axial and lateral compressive loads under fixed-fixed and fixed-free boundary conditions, respectively, and the relevant critical buckling loads were determined. Furthermore, the failure modes were examined via microscopic views taken from the damaged areas on the samples to fully understand the influences of NC particles on buckling characteristics. The findings demonstrated that the buckling behaviors of the samples were significantly affected by the introduction of NC particles. Compared with the composite samples without any NC particles, the composite samples with 1 wt% NC particles showed an increase of 21.12% and 25.33% in the axial and lateral critical buckling loads, respectively. However, the inclusion of NC particles with an amount that higher than 1 wt% showed a decreasing trend in terms of critical loads for both buckling loadings, which can be viewed as a measure of load-bearing capability. Moreover, the samples filled with 3 wt% NC particles exhibited a decrement on critical loads compared with those of samples without any NC particle filler. With the help of microscopic views, the failure modes were detected as matrix fragmentation and delamination for both buckling loadings.
