Fatigue strength of blunt V-notched specimens produced by selective laser melting of Ti-6Al-4V

•Blunt V-notched Ti-6Al-4V specimens were produced by Selective Laser Melting.•The fatigue strength was assessed using strain energy density method.•A very low notch sensitivity was observed for the analysed material.•ESEM analyses were used to study the fatigue failure mechanisms. Selective Laser M...
