Prediction of fracture in the vicinity of friction surfaces in metal forming processes
S. E. Aleksandrov, E. A. Lyamina Institute for Problems in Mechanics, Russian Academy of Sciences, Moscow, 119526
Abstract:
It is shown that the use of a fracture criterion containing a characteristic length of the flow region makes it possible to further develop the theory of fracture in the vicinity of the maximum friction surfaces in metal-forming processes, with allowance for an infinite equivalent strain rate arising near such surfaces. A model of perfectly plastic rigid solids is considered in formulating the criterion. It is noted that the approach can be extended to more complicated models of plastic solids.
Keywords:
fracture, friction, singularity, plasticity.
