摘要: A novel and rational approach based on Lie analysis is proposed to investigate the mechanical behaviour of materials exhibiting experimental master curves. Our relies idea that response associated with hidden symmetries; general objective this contribution reveal those symmetries from measurements construct constitutive laws them. This provides a priori two ways formulating data as well possibility predicting new curves material charts. The first part paper devoted presentation methodology. Afterwards, strategy applied uniaxial creep rupture Chrome-Molybdene alloy (9Cr1Mo) at different temperatures stress levels. Constitutive equations for responses are identified validated data.
