Abstract:The Hellinger-Reissner variational principle based hybrid finite element method (FEM) is developed and applied to study the nonlocal mechanics of plates and beams at a micro/nano-scale. For this purpose, a plane 8-node plate element termed as MHAS-24β with 24 independent internal force parameters is proposed to modelling the mechanical behaviors including static bending, free vibration and buckling. The Mindlin plate theory allows the use of generalized displacement to satisfy \({\text{C}}^{\text{0}}\) continu… Show more
