Modelling Plain Milling for Steel Specimen Along With Formation of Discontinuous Chip

Description

The total length of the specimen is 100 mm. Cumulative damage model which includes Ductile damage criteria alongside damage evolution, shear damage criteria are used to predict the damage initiation. While Johnson cook parameters are used to model its plastic behavior with damage evolution. Solution dependent variables were taken as unity. Temperature DOF were allowed at the integration points using Dynamic temperature explicit step. Formation of the chips strongly influence by the rotation speed of the tool. For the interaction the drill surface is connected with the nodes of the work piece using kinematic contact using thermal gap conductance, heat generation, and penalty as interaction property. The tool surface is coupled at the center while defining the COR at a same point while defining rigid constraint.
