MODAL ANALYSIS OF MWCNT REINFORCED AA5083 COMPOSITE MATERIAL

Material selection for structural application is the one of the major challenges faced by the designer because of the development of newer materials in the recent past. Aluminium alloy 5083 is widely used for structural applications due to its strength to weight ratio and resistant to corrosion environment. By adding, Multi-wall Carbon nanotube with Aluminium alloy 5083 in different compositions, the mechanical property of the composite material is enhanced. Mechanical properties of the material play a vital role for evaluating the frequency and deformation under different loading conditions. In this present work using Finite Element Method, free vibration study was carried out to find the natural frequency for the alloy and composite material. Modal analysis results show, the shifting of frequency than for the composite materials compared to the base alloy due to the addition of Multi-wall Carbon nanotube (MWCNT) and the results are validated using analytical method. The findings lead to selection of the operating conditions for the dynamic structural applications to avoid failure due to resonance.
