Hello Dear All,

    Thanks to Extreme Mechanics Letter, a new discusion of localized plastic deformation was published there. Three outlines of our work are:

      1. A new dislocation based consitutive model is built. It has a concise mathematical struture.

      2. Heat generated by plastic energy can be calculated by a mechanical version of Joule's law.

      3. Shear band and neck locations can be predicted by the mathematical model.
