Study of influence of notch root radius on fracture behaviour of extra deep drawn steel sheets

ABSTRACT Fracture tests are carried out on extra deep drawn steel CT specimens containing notches with different values of notch root radius (ρ= 0.07–0.75 mm). Experimental findings clearly show a critical notch root radius (ρc) below which the fracture toughness remains independent of ρ and above w...
