It should be noted that these calculations did not take into account the temperature effects associated with the adiabatic heating of the material in the shear zone, which should be taken into account in future calculations, according to the results of experimental studies. 4. Conclusions The authors modernized the drop-weight impact testing machine for dynamic shear tests. The dynamic shear tests were performed using specimens with two shear zones, that were made of structural steel 20, Hardox 450 high strength steel, and Armox 500T armored steel. The influence of the geometric parameters of the specimens, the direction of their cutting, and the strain rate on the behavior of the material under shear loading were determined. The fractographic analysis of the fracture surfaces of the specimens implied the strain rate affecting the fracture behavior of materials under shear loading conditions. The authors performed the numerical simulation of dynamic shear tests using the Johnson-Cook material deformation model. The results of the calculations and experiments were compared, as well as the strain rate effect on the obtained results was assessed. References Campbell, J., Ferguson, W., 1970.
