Finite Element Method for Cosserat Plates
For engineers and researchers modeling plate structures with microstructural effects, this provides a validated numerical tool for Cosserat plates, though the approach is incremental as it extends existing FEM techniques to a specific model.
This paper develops a finite element method for Cosserat elastic plates, proving existence, uniqueness, and convergence of the weak solution. Numerical validation shows the method achieves expected convergence rates and demonstrates that stress concentration factors around holes are smaller than classical values, with smaller holes exhibiting less stress concentration.
This paper presents the Finite Element Method for Cosserat plates. The mathematical model for Cosserat elastic plates is based on the calculation of the optimal value of the splitting parameter. We discuss the existence and uniqueness of the weak solution and the convergence of the proposed FEM. The Finite Element analysis of the clamped Cosserat plates of different shapes under different loads is provided. We present the numerical validation of the proposed FEM by estimating the order of convergence, when comparing the main kinematic variables with the analytical solution. We also consider the numerical analysis of plates with circular holes. We show that as expected the stress concentration factor around the hole is smaller than the classical value and smaller holes exhibit less stress concentration compared to larger ones.
