From Figure 1, we can conclude that the parallel bound solitons will form when [absolute value of [[lambda].sub.1]] [right arrow] [absolute value of [[lambda].sub.2]], while if the value of [parallel][[lambda].sub.1]| - |[[lambda].sub.2][parallel] increases, the elastic interactions between two solitons will happen.
By definition, back stress refers to long-range elastic interactions and effective stress to short-range elastic interactions.
