Title: Kayenta v. 1.0

Software ·
OSTI ID:1231183

The Kayenta material model (previously named the Sandia GeoModel, see The Sandia GeoModel Theory and User's Guide, by A.F. Fossum and R.M. Brannon, Sandia National Laboratories, Albuquerque, NM, 2004, SAND2004-3226) is a unified general-purpose constitutive model that can predict material response over a wide range of material properties and strain rates. The model strikes a balance between first-principles micro-mechanics and phenomenological, homogenized, and semi-empirical modeling strategies. Being a unified theory, the model can simultaneously model multiple failure mechanisms, or it can duplicate simpler idealized yield models such as classic Von Mises plasticity and Mohr-Coulomb failure. Since publication of the GeoModel Theory and User's Guide the model has been extended to support material softening and failure, as well as thermodynamic effects. These extensions have generalized the application space of the model, and it is now capable of accurately modeling metals and metal-like materials in addition to rocks and rock-like materials.
