Stress and strain-rate dependence of spall strength in two aluminum alloys
Conference
·
OSTI ID:5526606
The spallation behavior of 6061-T6 and AMg-6 aluminum alloys was studied as a function of loading stress and initial pulse duration for stress amplitudes ranging from 5 to 20 GPa and for pulse durations spanning the range of 0.06 to 0.9 ..mu..s. These experiments show that the spallation strength varies from about 0.7 to 1.4 GPa for strain rates varying from 0.15 to 1 ..mu..s/sup -1/ and for impact stresses from 5 to 20 GPa.
