The pure shear responses of Ti6Al4V alloy and Ti3Al2.5V alloy, conceived for unique applications in jet engine components, are compared using Digital Image Correlation technique from quasi-static (10 ?3 /s), medium strain rate 1 /s) high rates 3 /s). A series bespoke torsion tests have been performed on a screw driven mechanical system, fast hydraulic Instron machine Campbell split Hopkinson ba...

Auxetic cellular structures have the potential to revolutionise sandwich panel cores due their superior energy absorption capability. Because of negative Poisson's ratio, auxetics behave counterintuitively and contract orthogonally under an applied compressive force, resulting in a densification material vicinity load. This study investigates three compares absorbing characteristics in-plane ax...
