2. Soil behavior under cyclic loading
2.1 Experimental observations
Laboratory studies of soils show highly non-linear behavior under mechanical stress.
Conventional soil mechanics tests under monotonic loading enable us to plot shear stress-strain (or distortion) curves and define the different soil behavior domains (figure 9 ).
