Application of Ductile Fracture Criteria to Industrial Cutting Processes

Abstract:

Article Preview

Experimental and numerical studies of fracture prediction with Czech steel no.41 2050 are presented. Seven ductile fracture criteria were calibrated, applied to simulation of rod cutting and bolt head trimming operation and compared with experimental results of these processes, obtained in semi-industrial conditions in cooperation with our industrial partner. Movement of the cutting tool was stopped in predefined positions, so that a step-by-step mapping of subsequent stages of both processes were obtained at different specimens. By metallographic analysis of these, full view of plastic deformation and damage in the vicinity of the cutting region could be seen, and their comparison with the computational results was done.
