Case Le < Lme:	(a) fibers with decreasing tensile stress. The fiber is pulled out and its embedded length is decreasing.
	(b) Fibers with an increasing tensile stress; the embedded length of these fibers is greater than the fibers in case (a).
Case Le < Lme:	(c) Broken fibers; the reinforcement is zero.
	(d) Fibers with an increasing tensile stress, the embedded length of these fibers is smaller than the fibers in case (c).
