This paper investigates the electromagnetoelastic static properties of a sandwich doubly curved microshell subjected to multi-field loading. A refined higher order shear/normal deformable model is used, and the effect of small scale parameter on the bending results is studied.
This paper studies electromagnetoelastic static investigation of a sandwich doubly curved microshell subjected to multi-field loading based on a new thickness stretching included refined higher order shear/ normal deformable model. Modified-couple-stress-theory (MCST) is used for accounting small-scale-dependency. The numerical results are derived using an analytical method. The effect of small scale parameter in micro scale, initial electric and magnetic potentials and foundation parameters is studied on the electromagnetoelastic bending results. It is confirmed an enhancing in stiffness of small scale shell with an increase in micro length scale parameter. (c) 2022 China Ordnance Society.
