In the finite element method, the quality of the finite element mesh is crucial for accurate prediction of a product response to a load, or for determining its lifetime. The influence of finite element mesh quality was studied on the example of a thin plate bending. By comparing the theoretical and numerical results, the influence of some quality criteria was shown. The following criteria were used: aspect ratio, skewness and taper. It was found that, among the selected criteria, a combination of aspect ratio and skewness was least favourable for the results.
