摘要

In this paper, nonlinear dynamic equations are established based on the enriched first-order shear deformation theory (FSDT). Moreover, the nonlinear driven and companion strain modes are taken into account. The nonlinear dynamic equations are transformed into the nonlinear differential equations in terms of time by employing the Galerkin method. Consequently, the nonlinear dynamic analysis of CFRP/Ti/CFRP sandwich cylindrical shells with carbon fiber reinforced polymer (CFRP) face sheets and honeycomb titanium (Ti) core containing fluid under mechanical and thermal loads is performed. Effects of geometric, material, temperature, and fluid parameters on the vibration and dynamic responses are investigated.
