Description
Summary:in this paper, the most common types of damage to metal structures were considered. Their mathematical models were specified in Ansys. In the framework of the problem under consideration, the stress-strain state of the samples in the elastic zone and beyond is studied, i.e. beyond proportionality, in this case it is necessary to perform non-linear analysis. Nonlinear mechanical properties of the material were set in the program. As a result of the calculation, the authors obtained curves of the dependence of the maximum strain in the middle of the rack on the magnitude of the applied force. the calculation results show satisfactory convergence with the experimental results. Thus, it is possible to perform a similar assessment of the decrease in the bearing capacity of the rack for damage not studied in the full-scale experiment.
