Abstract
Experimental and theoretical studies are presented of the dynamic response of particulate materials containing interstitial pore fluid and interparticle bonding. Interparticle contact behaviors are significantly affected by the presence of pore fluid or cementation, and this produces differences in the dynamic material response when compared with dry, unbonded granular media. The dynamic behaviors of specific interest are the wave propagational characteristics of wave speed and amplitude attenuation. Relationships are established between these propagational variables and the material microstructure and interparticle load transfer mechanisms. Experimental studies employed dynamic photoelasticity to gather full-field information on stress waves moving through model material assemblies. Theoretical modeling used the discrete element method to simulate wave propagation in various computer generated assemblies.
