Kurzbeschreibung (Abstract)
As opposed to macro scale machining processes, the crystalline structure of commercially pure (cp) titanium plays an important role in micro machining processes. Finite element simulations of micro machining processes involve several challenges, since the workpiece material undergoes large deformations during chip formation and eventually material separation needs to be modeled. A robust implementation of the finite deformation multi-slip crystal plasticity model describing the material response is the basis of such simulations. One challenge is the determination of the active set of plastic slip systems. Standard explicit predictor-corrector formulations based on the Karush-Kuhn-Tucker (KKT) conditions often fail. In order to circumvent the explicit determination of the set of active slip systems, the KKT conditions can be replaced by a system of Fischer-Burmeister complementary functions.
