Free Vibration Analysis of A357 Alloy Reinforced with Dual Particle Size Silicon Carbide Metal Matrix Composite Plates Using Finite Element Method

In this work, the free vibration behaviour of A357 composite plate reinforced with dual particle size (DPS) (3 wt. coarse + 3 fine, 4 2 and fine) SiC is evaluated using finite element method. To end, first-order shear deformation theory (FSDT) has been used. The equations motion have derived Hamilton's principle solution obtained through condensation technique. A thorough parametric study was conducted to understand effect reinforcement weight fraction, boundary conditions, aspect ratio length-to-width geometry on natural frequencies A357/DPS-SiC plates. Results reveal significant influence all above variables frequency cases, fine particles displayed highest owing its higher elastic rigidity modulus. Further, increase decrease in geometry. Natural also decreases number edges. Lastly, increasing drastically improves © 2021 Polish Academy Sciences. All rights reserved.
