Strain gradient differential quadrature finite element for moderately thick micro‐plates

Summary In this study, we integrate the advantages of differential quadrature method (DQM) and finite element method (FEM) to construct a C 1 ‐type four‐node quadrilateral element with 48 degrees of freedom (DOF) for strain gradient Mindlin micro‐plates. This element is free of shape functions and shear locking. The C 1 ‐continuity requirements of deflection and rotation functions are accomplished by a fourth‐order differential quadrature...
