Hugoniot and shear strength of titanium 6-4 under shock loading

The shock and spall response of three industrially important hexagonal close-packed metals: magnesium, titanium and zirconium

“…Hopkins and Brar inserted manganin gauges into sectioned discs of Ti-6Al-4V to investigate the shear response of the material. They found evidence of shear-hardening with increasing shock stress [61]. Whereas Arrieta & Espinosa [65] investigated the effect of temperature on the HEL and showed that the HEL decreased with increasing temperature; similar results were found by Kruger et al [66] for the titanium alloy Ti-6-22-22S.…”

“…The equation of state for the most widely used titanium alloy, Ti-6Al-4V, has been well established by numerous studies using longitudinal stress gauges, with the HEL shown to vary between 2.1 and 2.8 GPa [59][60][61]. It is well known that oxygen content significantly increases the yield strength of titanium alloys owing to the formation of coherent α 2 particles [5,62].…”

High Strain‐Rate Material Model Validation for Laser Peening Simulation

“…The target assembly was securely fixed in a target tank with the impact surface situated perpendicular to the barrel of a 50 mm compressed gas/propellant gun, with launch velocities of 300–900 m/s. Details of the experimental technique are given in [29]. By varying the flyer plate impact velocity and the thicknesses of the flyer plate and target cover plate, strain rates in the range of 1–5 × 10 5 s −1 were achieved.…”

Deformation of a Low-Cost Ti-6A1-4V Armor Alloy Under Shock Loading

“…Hopkins and Brar (2000) reported that shear strength increased with increasing stress, ranging from 0.9 GPa at the HEL to 1.6 GPa at a stress level of 12.5 GPa. These values were obtained through simultaneous measurements of longitudinal and lateral stresses.…”
