THERMAL BUCKLING AND BENDING ANALYSES OF CARBON FOAM BEAMS SANDWICHED BY COMPOSITE FACES UNDER AXIAL COMPRESSION

The bending and critical buckling loads of a sandwich beam structure subjected to thermal load axial compression were simulated temperature distribution across layers was investigated by finite element analysis validated analytically. consisted two face sheets core, carbon fiber foam used as sheet core respectively for more efficient stiffness results. repeated with different materials reduce strain heat flux beams. Applying both ends fixed boundary conditions, induced stresses observed, steady-state performed, conduction through along their deformation nature based on the material properties combination core. best found reduction strain, addition aerogel significantly reduced without adding weight structure.
