There is an explanation of the logarithmic difference ratio law and the logarithmic modulus concept of nonlinear materials in this article,in which the mathematical model of the whole curve is set up based on the conclusion drawn from experiment and research:the logarithmic difference of relative stress and strain of nonlinear materials is a constant.The coefficient of strength and toughness given in this article are indexes of toughness of the nonlinear materials.The result of the research has an important[FQ(10?46(35,1)-W]academic value and theoretical significance.
