Abstract: In this paper few of the factors affecting the dynamic stability of a steel-alumina functionally graded sandwiched (FGSW) beam have been discussed. The equation of motion was derived using both Hamilton’s principle and finite element method. Floquet’s theory was used to separate the stable zone from the unstable. The effect of hub radius parameter and rotational speed on first mode and second mode instability region of FGSW beam have been studied following the power law and exponential law. The results indicated that increasing hub radius and rotational speed keeps the instability region away from load factor axis and hence remote the chances instability of the beam.
Keywords: Exponential Distribution, FGSW, load factor, Power law, Rotational speed, Hub radius, Stability.
Scope of the Article: Logic, Functional programming and Microcontrollers for IoT.
