Численное моделирование перспективных схем обработки образцов из листового проката

Abstract

In work with the use of methods of numerical modeling was solved the problem of determining of stress-strain state of specimens from light structural alloys on the basis of aluminum sheet metal during processing intense plastic deformation. For the realization of intensive plastic deformation of flat samples, it is proposed to use the method of pressing the groove. We consider the classical and alternative tooling of the mold. The alternative equipment has teeth in the form of half-cylinders. Changes in physical and mechanical properties due to changes in the internal structure of the treated flat samples are assumed. The advantages of the developed original rig before the classical execution are indicated. The obtained results of the numerical solution coincide with some error and correlate with one cycle of equal-channel angular pressing.
