摘要：

By the finite element method in a three-dimensional setting, the stress-strain state and the destruction of the anode block of a medium-temperature fluorine electrolyzer are numerically studied as a function of the temperature of the surrounding melt. Modeling is carried out within the framework of the phenomenological approach of solid mechanics. The behavior of the metal elements of the anode block is described by an elastoplastic medium and the limiting value of the intensity of plastic deformations is used as a failure criterion. The coke plate is modeled by an elastic-brittle medium, the fracture is described by a tensorpolynomial criterion that takes into account differences in the coke strength under compression and tension. Numerical simulation is carried out using the author's software package EFES 2.0. The influence of the distribution of porosity in a coke plate on its destruction has been studied.
