RAMP WAVE STRESS-DENSITY MEASUREMENTS OF TA AND W

Stress‐density (σ‐ρ) loading paths of both Ta and W under ramped compression were measured up to 300 GPa. For similar ramp loading conditions, σ(ρ) for Ta lies close to the cold curve and significantly below the Hugoniot, while σ(ρ) for W lies close to the Hugoniot and significantly above the cold curve. The elastic yield limit is reported for W and Ta with thicknesses 400–700 μm.
