Simulation of Strain Resistance in View of Abrupt Changes of the Strain Rate
The results of the numerical simulation of the strain resistance process during mechanical testing with an abrupt change of the strain rate and comparison of them with data obtained during experiments are shown. This approach was necessitated by the need to obtain relevant data for subsequent mathematical modeling of strain resistance. The analysis of this comparison provides an understanding of the accuracy of the numerical simulation of the forging process during the abrupt change of the strain rate. Experimental data were obtained for AMg6 aluminium alloy. The numerical simulation was performed within the framework of QForm software.
