description: The aim of the work is to substantiate the application of magneto-impulse loading for investigating the deformation characteristics of metals under high-speed deformation. During the research, magnetic field modeling and magnetic pressure calculation were carried out using COMSOL Multiphysics. Copper and aluminum were considered for the test samples used in the modified Hopkinson-Cook method. A model for measuring the high-speed mechanical properties of metals was created in ANSYS. Based on this model, graphs of mechanical stresses were obtained using aluminum and copper as samples. Additionally, the dependencies of the samples relative elongation on the applied load were graphed. Based on the obtained data on mechanical stresses and deformations, stress-strain curves for oxygen-free copper and aluminum alloy were constructed. The maximum possible deformation speeds for this model were determined. The analysis of the modeling results under magneto-impulse loading showed that the method allows determining the amplitude characteristics of the deformation process with an accuracy of 10â15%. It was also confirmed that the method can be used to achieve deformation speeds up to 104 s-1. This work is of great importance not only for scientists, but also for specialists involved in non-destructive testing of materials.
