Rate sensitive continuum damage models and mesh dependence in finite element analyses. [PDF]
ScientificWorldJournal, 2014 The experiences from orthogonal machining simulations show that the Johnson‐Cook (JC) dynamic failure model exhibits significant element size dependence. Such mesh dependence is a direct consequence of the utilization of local damage models. The current contribution is an investigation of the extent of the possible pathological mesh dependence.

Modulation-assisted high speed machining of compacted graphite iron (CGI)
Journal of Manufacturing Processes, 2013 Abstract The application of controlled, low-frequency modulation (∼100 Hz) superimposed onto the cutting process in the feed-direction – modulation-assisted machining (MAM) – is shown to be quite effective in reducing the wear of cubic boron nitride (CBN) tools when machining compacted graphite iron (CGI) at high machining speeds (>500 m/min).
