Paper Title:
Computer Simulation for the Milling Process of Cement Concrete in Pavement Planer
  Abstract

So as to design the pavement planer, it is necessary to study the milling performance of cement concrete. In this work, a coupled thermo-mechanical plane-strain large deformation milling finite element simulation is presented to analyze the cement concrete milling process and predict the stress and temperature field. A model for actual cutter and milling cylinder is set up. Chip separation is considered by applying shear fracture failure criteria and element deletion and adaptive mesh technique. Two contact pairs are defined. Contact pair 1 defines the milling path, and contact pair 2 defines to prevent the formed chip enter into the milling cylinder. The cutter surface friction and heat conduction are considered. The computation indicates that the maximal equivalent stress reaches 1.4MPa and maximal equivalent strain reaches 1.1 in the pavement, and maximal cutter temperature reaches 729°C. Improving suggestions are put forward.
