Thermal Buckling and Vibration Analysis of SMA Hybrid Composite Sandwich Beams

This work studies the buckling and free vibration behavior of Shape Memory Alloy Hybrid Composite (SMAHC) sandwich beams under a thermal environment. The consist layers reinforced with SMAs FGM core, they are simply supported at both ends. higher order theory is combined Minimum Potential Energy principle or Hamilton to derive governing equations problems, respectively. material properties beam assumed as temperature-independent (TID) temperature-dependent (TD). In last case, two different types distribution considered, namely uniform linear distribution. results based on proposed formulation verified against reference literature, very good matching. A parametric study checks for influence effective parameters such thickness-to-length ratios, volume fraction powers, initial strain, SMA wires, temperature overall mechanical response selected structural member, useful insights from design standpoint.
