    This page is a repository for resources and conversations between program participants. It is meant as a supplement to the official program page that features the full program description, video and audio recording of all related KITP seminars and discussions. These are archived along with materials associated with those seminars and discussions.
    Program participants and researchers in related areas who are following the program are encouraged to edit these pages and add new pages to include additional links to papers and engage in discussions over distance.

    Non-crystalline Plasticity
    {zone_sm.jpg}
    Shear Transformation Zone (STZ) Theory is a set of equations that build upon ideas developed by Ali Argon, who coined the term "shear transformation zone" to describe metallic glass deformation, and related ideas developed by Frans Spaepen who developed a free volume theory of deformation in metallic glass. The STZ theory begins with the following hypotheses:

    DynamiclinkDynamic Ruptures in
    Faulting is a process that disrupts material continuity and creates zones of relatively compliant damaged rock bounded by material discontinuity interfaces. In addition, active faulting over geological times brings into contact materials that were originally separated and are thus likely to have different elastic properties. There are fundamental differences between properties of dynamic ruptures on faults that do or do not separate different elastic solids.
    On a planar fault between solids with identical elastic properties, there is no coupling between slip and changes of normal traction. On the other hand, mode II (in-plane) rupture along a material interface generates local changes of normal stress that are proportional to the spatial derivative of slip. This produces dynamic dilation at the tip that propagates in the direction of slip on the more compliant side of the fault and dynamic compression at the tip propagating in the opposite direction.
