ABSTRACT

ABSTRACT: A study was conducted using Dynamic Discontinuous Deformation Analysis to model the joint compliance of a model material developed for the Topapah Springs welded tuff located at Yucca Mountain, Nevada. The model used physical properties measured from laboratory tests, a typical or average aperture, and a simulated joint roughness. The degree of joint closure, or remaining aperture, could be controlled by applied stress level. Full closure of the joint was ultimately obtained in the model, and the results compared well with laboratory compliance tests.
