چکیده
This study investigates the thermoelastic behaviour of laminated composite beams with symmetric (0/90/0) and asymmetric (0/90) layerups subjected to sinusoidally distributed thermal line loads. A quasi 3D shear deformation theory incorporating parabolic and trigonometric through thickness functions based on Reddy’s refined model forms the core analytical framework. The governing equations are derived from the principle of virtual work and solved in closed form via a Navier’s type series. The classical beam theory and first order shear deformation theory are employed solely for comparative analysis. The thermal line load model, representing realistic non-uniform heating scenarios enables assessments of coupling effects due to laminate asymmetry. Results reveal that asymmetric configurations exhibit significant thermal coupling leading to higher displacements and stress concentrations, while symmetric laminated beam offer improved thermal stability. A MATLAB based computational tool supports the analysis. The findings underscore the critical role of stacking symmetry in mitigating thermal deformations, guiding the design of reliable composite structures for thermally demanding environments.
