TL;DR: In this paper, a displacement-based finite element formulation associated with a novel third-order shear deformation plate theory was developed, taking the desirable properties and advantages of the TSDT theory as its kinematics of displacements are derived from elasticity theory rather than the hypothesis of displacement.
