英文摘要The well-known Kirchhoff or classical plate theory (KPT) is a powerful tool for analyzing the mechanical behavior of thin plates. The Mindlin plate theory (MPT) considers shear deformation and rotary inertia (which are both excluded in the KPT), and is capable of applying to moderately thick plates. However, the solutions derived from the MPT are quite complicated. In this paper, a thickness torsion locking first- order shear deformation plate theory or simplified Mindlin plate theory (SMPT) is introduced to oversome the shortcomings of both the KPT and MPT. In the presence of shear deformation and rotary inertia, a fourth-order governing partial differential equation is derived. To ensure the consistency between the order of the governing equation and the number of boundary conditions, the twisting moment boundary condition is converted to an effective shear force, similar to the treatment in the KPT. The static bending and free vibration of rectangular plates with typical boundary supports are analyzed using Navier's and Levy's methods, respectively. A comparison of the deflection and natural frequencies is conducted among the KPT, SMPT and MPT. The effect of aspect ratio and thickness-to-length ratio on the deflection and natural frequencies is examined. The results demonstrate that SMPT is efficient and applicable to thin and thick plates. The SMPT can be further extended to with multi-field and size behaviors.
