“…To describe the various structural responses, many scholars have developed abundant deformation and failure theories of composites based on the existing metal theory. The buckling and thermal buckling [ 3–5 ] are the crucial evaluation indexes of the stability of composite laminates. The complexity of the constitutive relationship of composite materials further increases the difficulty of the stability research.…”

In this article, a novel experimental device that combines bending and shearing was proposed to investigate the load‐bearing performance of large‐size C‐beam structures against bending‐shear buckling, allowing for the adjustment of bending‐shearing ratio. Three different bending‐shear coupling conditions were performed for test loading, and the strain gauges were carried out to detect the strain distribution for postbuckling performance of the large‐size C‐beam. The finite element models were established by ABAQUS/Explicit to explore the stress distribution and damage evolution during postbuckling failure. Thereafter, the LaRC05 and Hashin criterion was used for failure prediction of the large‐size C‐beam in numerical simulations. The experiment results show that the large‐size C‐beam has excellent postbuckling bearing capacity regardless of bending or shear resistance. Based on the results, the failure numerical model considering the stress distribution in postbuckling and the finite element calculation were in good agreement with experiments. This study can offer a practical reference for the postbuckling performance of large‐size C‐beam structures after bending‐shear coupling.

“…Mahabadi et al [12] and Malekzadeh et al [13] performed extensive work on investigating the influence of parametric, e.g., pre-strain, volume fraction, distribution form of SMA, and geometric parameters on dynamic behavior. Nonlinear free vibration response and active buckling control in composite plates were further examined to conduct an inquiry into thermally buckling and post-buckled composite plates embedded with SMA wires [14][15][16][17][18][19][20][21][22].…”

As an extension of conventional gradient, anti-symmetric oblique coupling gradient has a superior modal modification ability on composite laminates embedded with pre-strained shape memory alloys (SMA) wires, which is beneficial to suppress modal resonance of composite laminates in the thermal environment. This paper presents an anti-symmetric oblique coupling gradient model of SMA along the thickness direction. That is, the gradient model of SMA wires’ orientation and the positive and negative gradient model of SMA volume fraction. Considering the internal force of composite laminates composed of the pre-strain recovery force of SMA and the thermal expansion force of the substrate, the free vibration equation of composite laminates with additional internal forces energy is derived from first-order shear plate theory and Hamilton principle. The influence of coupling gradient parameters on the thermal modal performance of SMA composite laminates is analyzed and verified by experiments. The proposed anti-symmetric oblique coupling gradient SMA wires’ distribution form effectively exerts the recovery stress generated by SMA tensile pre-strain, i.e., effectively improves the stiffness and critical buckling temperature. Coupling gradient distribution broadens the frequency modulation range, which makes the fine regulation of the natural frequency and critical buckling temperature feasible.

“…They comprehensively examined the effects of stacking sequence of layers, thickness to span ratio, degree of anisotropy, volume fraction, and pre‐strain of SMAs on the buckling temperature of composite beams. Yas et al [ 28 ] explored the influence of SMA wires on the critical buckling temperature of trapezoidal composite plates. The governing equations were derived based on first‐order shear deformation theory (FSDT), and the recovery stress was estimated by Brinson's model.…”

Two main goals are followed in the present work. The first objective is the development of a simple analytical model based on piecewise low‐order shear deformation theory (PLSDT) for the natural frequencies of sandwich plates made of flexible core with temperature‐dependent mechanical properties and laminated composite face sheets with embedded pre‐strained shape memory alloy (SMA) wires. Brinson's model is applied in this research to estimate the recovery stress produced by SMAs. A comparative study is performed to show the ability of the proposed model to offer high solution accuracy at low computational costs. Specifically, the results of the present research exhibit less than a 2% difference from those obtained from the mixed LW/ESL models in the framework of Carrera's unified formulation (CUF). As the second goal, the influences of some parameters such as the pre‐strain of SMAs, the volume fraction of SMAs, and core thickness on the fundamental frequencies of SMA‐reinforced sandwich plates are examined. The results reveal that depending on the geometric parameters and operating temperature, SMAs may have constructive or destructive effects on the free vibration of sandwich plates.
