Abstract :
Pull-in instability of Boron Nitride Nano-Beam (BNNB) under the combined
electrostatic and Casimir force as nano-switch is presented. Using Euler-Bernoulli Beam
(EBB) theory, nonlocal piezoelasticity theory, von Karman geometric nonlinearity and
virtual work principle, the nonlinear governing di erential equations are obtained. The
equations are discretized by two types of numerical methods, namely the Modi ed Adomian
Decomposition (MAD) method and Di erential Quadrature Method (DQM). Analysis
of lower pull-in voltage values is considered for nano-switches with di erent boundary
conditions. The detailed parametric study is considered, focusing on the remarkable e ects
of nonlocal parameter, beam length, boundary condition, geometrical aspect ratio and gap
distance on the behavior of the pull-in instability voltage. The obtained results of DQM
and MAD are compared with published relevant study. This work is hoped to be useful in
designing and manufacturing of Nano-Electro-Mechanical Systems (NEMS) in advanced
applications such as high-tech devices and nano-transistors with great applications in
computer industry
