Measurement of the temperature profile during shear band formation in steels deforming at high strain rates

Formation and microstructure of localized shear band in a low carbon steel

“…These results are consistent with the observation of Costin et a1(1979)(4) in cold rolled steel that the shear band developed at a critical strain of 0.3, and Ctifton(1983)(5) in hot rolled steel at the critical strain of O.8-1.0. These are similar Co results obtained by Hartley et al (6).…”

“…Hartley et at (6) in CRS steel. They pointed out that the fibrous nature of the fracture is due to the occurrence of local heating from the large dynamic strain in the shear band.…”

On the dependence of the dynamic crack tip temperature fields in metals upon crack tip velocity and material parameters

“…The switch by Duffy and coworkers (Marchand and Duffy, 1988;Hartley et al, 1987;and Duffy 1984) and Fuller et al (1975) to InSb detectors from the GeCu detector of Moss and Pond (1975) reflects the desire to produce the greatest sensitivity in the range of wavelengths expected in addition to maintaining the smallest rise time possible. InSb offers the best balance of these two objectives.…”

Model Describing Material-Dependent Deformation Behavior in High-Velocity Metal Forming Processes

“…This localization tendency is especially pronounced when adiabatic conditions prevail. High speed deformation has been studied by many authors, such as Trötzschel et al (1997) and in connection with heat generation in adiabatic shear bands by Clifton et al (1984); Hartley et al (1987); Marchand and Duffy (1988); Batra and Liu (1990); Zhu and Batra (1992); Tugcu (1995) and Batra and Stevens (1998).…”
