COMPARATIVE ANALYSIS OF THE ACCURACY OF THE CALCULATION RESULTS OF A THIN BENDABLE PLATE USING VARIOUS FORMS OF FEM
The article presents the results of a comparative analysis of the accuracy of a thin bending plate according to the FEM in the form of a classical mixed method (CSM) and based on the FEM in dis placements using the SP LIRA SAPR. The analysis of calculation results for plates with several types of boundary conditions and representation in the form of an ensemble of rectangular finite elements with 3 unknowns at each node is performed. Based on the results of calculations, a conclusion was made about the accuracy and correctness of calculations using two forms of the FEM. Graphs of convergence of calculation results are given.
