Description
Summary:Using the method of finite elements in a three-dimensional formulation, this study examines the stressed-deformed state and fracture of the anode block of a medium-temperature fluorine electrolyzer, while varying the temperature of the surrounding melt. The study utilizes a phenomenological approach in solid mechanics to model the behavior of the metal elements of the anode unit as an elastoplastic medium, with the limit value of plastic deformations serving as the fracture criterion. The coke plate is modeled as an elastic-brittle medium, with a tensor-polynomial criterion used to describe its fracture, accounting for differences in coke strength during compression and tension. The study employs the author’s EFES 2.0 software for numerical modeling and investigates the impact of porosity distribution in the coke plate on its fracture.
