摘要: The following research work deals with the size-dependent dynamic instability of suspended nanowires in presence Casimir force and surface effects. Specifically, Casimir-induced nanostructures circular cross-section cylinder-plate geometry is studied. Following Gurtin–Murdoch model nonlocal elasticity, governing equation motion for derived. To express attraction geometry, two approaches, e.g. proximity approximation (PFA) small separations Dirichlet asymptotic large are overcome difficulties solving a nonlinear problem, step-by-step numerical method utilized. effects parameter, energy vacuum fluctuations on characteristic adhesion time It observed that phase portrait exhibit periodic homoclinic orbits.
