【标题】Fracture behavior at crack tip - a new framework for cleavage mechanism of steel.pdf(710.99 KB)
【摘要】The fracture behavior at crack tip was analyzed based on: (1) observations of fracture surfaces and measurementsof local critical parameters for cleavage of three point bending (3PB) precracked specimens of C-Mn steel, (2) detailedobservations of configuration changes at precrack tips by metallographic cross sections in specimens unloaded at variousapplied loads, (3) sophisticated FEM calculations of distributions of stress, strain and triaxiality and simulations ofshort cracks initiated and ext...
