Study of the efficiency of the compensating load method in the calculation of systems with angular hardening connections

The efficiency of the algorithm for calculating systems with hardening (softening) angular bonds is analyzed using an algorithm that combines the advantages of the finite element method in the form of a classical mixed method and the method of compensating loads. The number of iterations required to calculate systems with nonlinear connections of different stiffness with the same accuracy is chosen as the parameter for evaluating efficiency. An example of calculating a problem with nonlinear elastic supports of various stiffness, necessary for efficiency analysis, is given
