Stability, bifurcation, and softening in discrete systems: A conceptual approach for granular materials
Matthew R. Kuhn, Ching S. Chang
Matrix stiffness expressions are derived for the particle movements in an assembly of rigid granules having compliant contacts. The derivations include stiffness terms that arise f…

Measurement of higher-order stress-strain effects in granular materials undergoing non-uniform deformation
Matthew R. Kuhn, Ching S. Chang
Discrete element (DEM) simulations demonstrate that granular materials are non-simple, meaning that the incremental stiffness of a granular assembly depends on the gradients of the…
