Deformation of titanium alloy Ti-6Al-4V under dynamic compression

► Friction has a quantifiable effect on the localised deformation. ► Compression rate has a quantifiable effect on the localised deformation. ► When the compression degree is large, the localised deformation could even reduce. ► Increasing friction causes the shear stress region to move outwards. ► Likelihood of fracture tendency when friction and compression rate increase.
