Our paper on the Mechanical threshold stress (MTS) model for 6061-T6 aluminum has been accepted by JoMMS. There are several things of interest in the paper:
1) The use of a phonon drag model to predict the sharp increase in flow stress at strain rates above 10,000 /s. This behavior is seen in a number of materials and is hard to fit using standard power law plasticity models. Our model does a good job in this regard.
