Factors Affecting the Incremental Stiffness of Particle Assemblies

by Matthew R. Kuhn, Univ of Portland, Portland, United States,



Document Type: Proceeding Paper

Part of: Mechanics Computing in 1990's and Beyond

Abstract:

A simple numerical experiment was performed on an assembly of densely packed spheres in order to investigate the factors that affect an assembly's incremental stiffness. The experiment provides quantification and insight into the relative importance of these factors: contact stiffnesses, particle rotations, variations of the particle translations from their average values, and frictional slipping at the contacts. Although the contact stiffnesses will surely affect an assembly's stiffness, the test results show the great effect of particle rotations, nonuniform translations, and frictional slipping.
