Soils exhibit nonlinear shearing stress-shearing strain behavior as the strain level increases from nearly elastic to plastic conditions. Experimental shearing stress-strain data were approximated by a Ramberg-Osgood mathematical curve which may be incorporated into analytical procedures. The method of characteristics was presented as one analytical method for studying dynamic behavior of soils, fluids, and structures including nonlinear soil behavior, inelastic slip, and transient pore pressures in one and two dimensional systems. Several types of model studies involving soil-structure interaction were presented to illustrate the new method of holgraphic interferometry and to emphasize the importance of test and construction details on the effectiveness of dynamic soil-structure interaction. The importance of positive contact between the foundation block and soil along the vertical faces was noted.
