Abstracts: | The problem of determining the temperature fields and parameters of the stress-strain state in metal during processing in a casting and forging module is considered. The principle of operation of this device combines the crystallization of the metal melt and subsequent deformation into a given profile by ensuring the mobility of the walls of the mold. A mathematical model of material deformation is constructed taking into account friction and heat dissipation on the contact surfaces with the tooling. The material is supposed to be thermo-visco-plastic, with temperature-dependent properties. A difference numerical method for solving the problem is described. In computational experiments, fields of temperature, displacement velocities, stresses and deformations were obtained for the production of a strip of aluminum alloy AD0.
