Experimental and Theoretical Response of Multiphase Porous Media to Dynamic Loads.
Abstract
This report summerizes the current status of a combined experimental and theoretical investigation of the response of multiphase porous media to dynamic loading. This completes the first year of a planned three year investigation. Under the experimental portion, laboratory test were devised and conducted to measure the compressibility of soil and rock grains containing a large percentage of microporosity. Test were also developed to model liquefaction due to uniaxial strain loadings and to measure the amount of late-time consolidation as a function of the loading parameters. Finally, a test apparatus to measure fluid friction and energy absorption in porous media under specified flow conditions, including laminar, transient, and turbulant, was designed and constructed. This is currently undergoing evaluation. Under the theoretical portion of the work, derivations and computational algorithms to model the response of saturated soils and rocks to uniaxial and hydrostatic compressional loads were developed. The general purpose two-phrase code TPDAPII was completely revised to include more realistic plastic and elasto-plastic material models and more efficient computational algorithms. Lastly, theoretical derivations were completed for inclusion in the general purpose multiphase code MPDAP, to be written during the following year's effort.
