If you have a question about this talk, please contact Stephen Walley.

This talk is on a recent work in charactering the relationship between energetic material properties and the catastrophic debonding of particle/binder interfaces, with emphasis on the inertial effects in a viscoelastic binder. The theoretical analyses are linked to two experimentally observed phenomena: (1) chaotic motion of PBX 9501 during slow heating, and (2) sudden stress drop and localized deformation during compression of a PBX 9501 Brazilian disk.

This talk is part of the Surfaces, Microstructure and Fracture Group series.
