A comparison of implementation of linear and nonlinear constitutive models in numerical analysis of layered flexible pavement
It is generally accepted among pavement engineers that the granular layers in flexible pavement behave in a nonlinear mechanical way. Existing literature documents different constitutive equations to model this nonlinearity. This paper compares four well-known constitutive models: linear elastic, K−...
