Figure 7. Schematic diagram showing the development of strain during compaction and decompaction. (A) Compaction history over time during which a circle with a unit radius undergoes deformation. The resulting finite strain ellipse is characterized by a shorter 
axis and a constant 
axis, where 
are the principal strain axes and e is the strain value. The graph shows the relationship of 
magnitude over time. (B) The reverse of (A) to show the effect of decompaction; 
from the finite compaction stage is the reciprocal of 
from the finite decompaction stage.
