چکیده انگلیسی
The effects of temperature on the dynamic yield and spall behaviors of two aluminum alloys, 2024-T4 and 7075-T6, were investigated using plate-impact spall experiments, including real-time measurements of free surface velocity. A heating device was designed that was coupled to a light gas gun. Hugoniot elastic limit (HEL) strength and spall strength were calculated using the free surface velocity profiles. Normalized HEL strength and normalized spall strength of 2024-T4 and 7075-T6 exhibited a similar linear decrease with increasing temperature. Comparison of aluminum alloys and pure aluminum demonstrated differences in the correlation of HEL strength and spall strength. This difference was linked to the different underlying mechanisms of damage.
