Dynamic deformation of al under shock loading
WebThe second present the results of studies of the dynamic strength of important issue is related to the effect of temperature 15Kh2NMFA structural steel under loading by shock on the resistance to high-rate deformation and frac- compression pulses of submicrosecond duration at ture. WebTo date, considerable research has been devoted to assessing the strength of solids at high strain rates. Under certain conditions, materials behave very unusually. Experiments with shock waves found that the stress of the plastic flow as the temperature increases may not decrease, but increase.
