Abstract EN
In this paper, a gradient stable node-based smoothed discrete shear gap method (GS-DSG) using 3-node triangular elements is presented for Reissner–Mindlin plates in elastic-static, free vibration, and buckling analyses fields.
By applying the smoothed Galerkin weak form, the discretized system equations are obtained.
In order to carry out the smoothing operation and numerical integration, the smoothing domain associated with each node is defined.
The modified smoothed strain with gradient information is derived from the Hu–Washizu three-field variational principle, resulting in the stabilization terms in the system equations.
The stabilized discrete shear gap method is also applied to avoid transverse shear-locking problem.
Several numerical examples are provided to illustrate the accuracy and effectiveness.
The results demonstrate that the presented method is free of shear locking and can overcome the temporal instability issues, simultaneously obtaining excellent solutions.
