Abstract: A method for evaluating the rheological properties of at least one gel, consisting in determining the extent of the plastic domain in stress ?c??p, and in strain ?c??p, the determination being carried out according to the steps: subjecting at least one sample of at least one gel to oscillating mechanical stresses at a fixed frequency, determining and plotting curves of the elastic modulus G? and the viscous modulus G? as a function of the strain and stress, determining ?c and ?c at the point of intersection Xc of the curves of G? and G? under stress and strain, determining ?p and ?p by fixing an arbitrary value of G? (G?x) that is defined as the entry value into the plastic domain, and calculating ?c??p and ?c??p.
