“…The location of heat input and the temperature distribution of the beam will influence the critical buckling temperature of a composite beam. George et al [21] experimented with the thermal buckling behavior of laminated glass fiber reinforced epoxy-based composite beam under non-uniform heat input to estimate the critical buckling temperature of the studied beam. Muc et al [22] investigated the postbuckling characteristics and stability loss of multilayered composite beams.…”

The present study focuses on the numerical modeling of the thermal buckling behavior of tapered laminated composite beams validated by experimentation. Lagrange's energy‐based governing differential expression was derived utilizing classical laminated plate theory and higher‐order shear deformation theory to analyze the tapered composite beam's thermal buckling property. The uniform temperature rise environment is employed to estimate the critical buckling temperature of the tapered laminated composite beam. The obtained results from the numerical approaches were validated with the experimental results and the previous results obtained from the literature associated with the fundamental frequencies of the structure and critical buckling temperature. The parametric study was incorporated in this present work to investigate the influence of the structural parameters and the geometrical parameters like taper angle, ply orientation, aspect ratio, and boundary constraints of the beam.

“…11 Similarly, experimental investigations were also made to investigate the buckling behavior of a laminated composite beam under different types of temperature distributions. 12 Studies on the vibro-acoustic response of heated structures under a steady-state mechanical excitation are limited compared to studies on heated structures' static, buckling, and dynamic behavior. A comprehensive analysis of the buckling and dynamic (vibration and acoustic) behavior of a uniformly heated isotropic plate and their numerical study revealed that elevated temperature significantly influences the resonant vibration and sound response amplitude.…”

The influence of non-uniform heating on the anisotropic plate’s dynamic and acoustic response characteristics is investigated numerically. The effect of non-uniform heating on the plate is accounted in the form of pre-stress developed on the plate due to non-uniform heating of the plate. The influence of structural boundary conditions, nature of temperature variation, and level of temperature on vibration and acoustic response characteristics are investigated in detail. Thermal buckling strength and fundamental buckling mode are highly sensitive to the nature of temperature variation across the plate. Free vibration mode shapes of the plates with high aspect ratio and free edges are changing their pattern with an increase in temperature. The resonant amplitude of sound power radiated associated with a particular mode is dominated by vibration nodes and anti-nodes shifting relative to the excitation location. Further, an increase in sound power level with an increase in temperature is observed clearly in the lower octave frequency bands.

“…George et al, 4 George, and Jeyaraj 5 have conducted theoretical and experimental research on the buckling strength of a beam and showed that critical buckling strength is influenced by the in-plane temperature variance controlled by the heat source location. Raphael et al 6 showed that the mechanical buckling strength is significantly improved with the slight addition of carbon nanotubes (CNT) in a glass fibre reinforced composite beam.…”

The current study reports the thermal buckling, vibration and acoustic characteristics of functionally graded graphene polymer layer composite plates subjected to the in-plane temperature variance. The macroscopic properties of the composites are evaluated using the modified rule of mixtures to compute the layer-wise properties of an functionally graded graphene polymer layer composite plate. The critical buckling temperature is computed and compared for various functional gradings, boundary conditions and in-plane temperature variances. The in-plane temperature variance showed a major impact on the critical thermal buckling temperature and respective mode shapes. The vibro-acoustic behaviour of the functionally graded graphene polymer layer composite plate is investigated and documented keeping critical buckling temperature as a function. With an increase in thermal load and the nature of in-plane temperature variance, the vibro-acoustic results showed significant difference in velocity and acoustic response. For functionally graded graphene polymer layer composite plate with one free edge, the difference was statistically significant as indicated by an octave band plot. We conclude that the portion of the functionally graded graphene polymer layer composite plate that is subjected to the higher temperature in an in-plane temperature variance, as well as the nature of the boundary conditions may exacerbate the effect of in-plane temperature variance and are crucial in predicting vibro-acoustic characteristics.
