In this study, a dynamic analysis method for flexible multibody systems using Reissner–Mindlin shells was developed, and an edge center-based strain smoothing mixed interpolation of tensorial components (MITC) method that described the deformation of flexible shells was presented. Three primary achievements were completed. First, a new dynamics equation for Reissner–Mindlin shells based on the floating frame of reference formulation was modeled, in which the coupling of the bending and membrane deformations with rigid motion was considered comprehensively. Second, an edge center-based strain smoothing (ECSS) method that effectively improved the membrane and bending behavior for MITC3 elements was proposed. Third, the ECSS method was designed to construct a linear strain field within an element to ensure the strain consistency at the junction center of the element, resulting in a smoother stress field. The superior performance of the proposed method was verified by convergence analyses, and its advantages for flexible multibody dynamics analyses were also highlighted numerically.
