Influence of axial compressive loads on buckling and free vibration response of surface-modified fly ash cenosphere/epoxy syntactic foams

Abstract: This work deals with experimental buckling and free vibration behavior of silane-treated cenosphere/epoxy syntactic foams subjected to axial compression. Critical buckling loads are computed from compressive load–deflection plots deduced using universal testing machine. Further, compressive loads are applied in the fixed intervals until critical loading point on different set of samples having similar filler loadings to estimate natural frequency associated with the first three transverse bending modes. Increa… Show more

“…The inelastic response of the beam is substantially impacted by changes in the intensity of the axial load [10][11][12]. Among the most probable structural failure, buckling is caused due to application of axial load [13][14][15][16]. Therefore, a comprehensive determination of the maximum sustainable buckling load is necessary to avoid this failure.…”

“…To address the eco-friendly disposal of fly ash many researchers have contributed their efforts to developing lightweight composites. [15][16][17][18][19] Utilization of these inexpensive fly ash cenospheres as a reinforcement in the polymer matrix brings out excellent mechanical properties and thermal stability for intermediate to high-temperature applications. [19][20][21][22][23][24][25] Several studies have reported secondary reinforcement to the syntactic foams to improve their mechanical, and thermal properties.…”

“…By bonding inorganic fillers with -Y groups on the surface and polymers, the bonding between inorganic fillers and polymers is improved. [21][22][23][24][25][26] Hence, the effect of the silane coupling agent on the treatment of inorganic fillers depends on two factors. The first is the extent of reaction between -Si(OR) 3 groups in the silane coupling agent after hydrolysis and inorganic fillers.…”
