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...

Acoustic signals in the megahertz to gigahertz regimes enable applications phononic, electric and photonic circuitry. Hence, advancement these multi-physics circuitries requires studying transmission of elastic waves micro/nano-electromechanical systems. Therefore, our work investigated flexural unidirectional phononic waveguides coupled nano-electromechanical drumhead resonators. In particular...

We study the compression of viscous filaments at constant velocity. If slender enough, the filament bends, a viscous analogue of Euler elastic buckling. We measure the characteristic time of this viscous buckling and discuss the link with the elastic critical compression. We show that the analogy only holds in the limit of large capillary numbers. Otherwise capillarity has a stabilizing effect,...

design and construction of efficient and economic reinforced concrete (r.c.) hyperbolic cooling towers have driven the engineers toward the design of tall and thin-shell towers which have considerable high slenderness aspect ratio. consequently, the shell of r.c. cooling towers with relative high slenderness aspect ratio is extremely prone to buckling instability due to wind loading. to increas...

the spline finite strip method (s.f.s.m.) for buckling analysis of plates and plate assemblies subjected to longitudinal compression and bending, transverse compression as well as shear is described. the method allows for the boundary conditions. local buckling coefficients of plates with different boundary conditions under compression, bending and shear are calculated. convergence studies with...
