the concept of introducing critical repeated stress level into the carter model is expounded based on the critical state soil mechanics; and the carter model is modified.
william rankine, a scottish engineer and one of the fathers of thermodynamics, was the first to explain how these repeated stress reversals could cause cracks to propagate.
