La loi de Rowe permet de tracer un comportement repère
des essais trianxiaux drainés en q/Mp( ) et
Rowe Law allows us to draw a reference behavior in q/MP( ε 1 )

5.5.2. The mathematical model
A mathematical model used to represent the set of experimental standards was
proposed by Favre and Hachi [HAC 01].
In the (ε v - ε 1 ) plane, the rather complex model represented by equation [5.19]
includes five parameters. Its transcription on the (q - ε 1 ) plane comes from Rowe's
