О выборе уравнения состояния обрабатываемого материала для моделирования процесса резания методом конечных элементов

The deep review of flow stress equations applicable for modelling of metal cutting is represented in this paper. It is show that there a lot of different forms of flow stress equations, but most of them defined only in narrow ranges of strain, strain-rate and temperature. This is one of the reasons of quantitative disagreement between finite element modeling and experiment.
