Effective temperature rise during propagation of shock wave and high-speed deformation in metals

Investigation of the crater-like microdefects induced by laser shock processing with aluminum foil as absorbent layer

“…A temperature increase T 2 within the specimen is determined by converting a fraction of the plastic deformation into heat [21,24]. This deformation-induced temperature increase is expressed as:…”

Effect of irradiation-induced plastic flow localization on ductile crack resistance behavior of a 9%Cr tempered martensitic steel

“…This leads to an increase of local temperature (adiabatic process) that might promote annealing of the irradiation defects [2]. During high strain rate deformation, a significant increase of the effective temperature is usually expected as a result of intense heating due to the dissipation of plastic deformation work [85][86][87]. Due to experimental difficulties for measuring temperature at the crack tip during a very short duration, there are not many reported quantitative data on temperature elevation.…”

Temperature rise during differential speed rolling

“…The other factors were the energy input caused by frictional heat and the energy loss by non-isothermal condition due to the temperature rise of the sample. Considering the fact that 90% of the deformation work was converted into heat and 50% of the frictional heat was transferred to the sample [10][11][12][13], the energy-based state equation during DSR is expressed as follows,…”
