    Description

    Ph.D. project - Henrik Hallberg Jensen
    The main objective of this Ph.D. project is to develop special test methods and procedures for material and interface properties in the full range of temperatures up to the melting point. Based on the results of testing, mathematical models will be developed for the basic material properties including the electrical resistivity, thermal conductivity, heat capacity and mass density as functions of the temperature, and the flow stress as a function of the temperature, strain and strain rate, as well as for the interface properties including the contact resistivity and thermal conductivity as functions of temperature, pressure and the base metal properties. These models will be implemented into the FEM program for verification of the numerical models for resistance welding of the selected metals which are frequently used in the Danish industries.
    Henrik Hallberg Jensen stopped the project due to personal reasons.
