| In this paper, a numerical strategy is presented to analyze the bending and buckling responses of aluminum composite plates (ACPs) reinforced by nano-scale silicon carbide and micro-scale discontinuous fiber-like silicon carbide. First, the equivalent mechanical properties of multiscale fillers-reinforced ACPs are predicted using a nested micromechanics-based approach. It is considered that discontinuous fibers are randomly dispersed into the hybrid material system. Thereafter, the finite element (FE) method is employed to evaluate the bending and buckling characteristics of hybrid ACPs. The influences of volume fraction of nano-filler, aspect ratio, alignment and volume fraction of micro-filler, shape and thickness of the plate on the ACP structural responses are examined. The results indicate that reinforcing the metal-based structures by nano/micro multiscale silicon carbide fillers significantly improves their load bearing capacity. The hybrid ACPs with higher volume fractions of multiscale fillers possess larger critical buckling loads. It is observed that by (i) increasing the aspect ratio, and (ii) aligning discontinuous fiber-like silicon carbide, the critical buckling load of ACP is increased, while its maximum deflection is decreased. | ||
