2.1 Rheological properties of polymers
Figure 5 shows the stress σ - strain ε curves of various polymers: they generally comprise three parts:
an initial phase of strongly increasing stress, corresponding to small elastic and viscoelastic deformations, which disappear rapidly after the specimen has been discharged; to a first approximation, this range is characterized by the slope of the curve, which can be identified with the Young's modulus E, whose value depends on the deformation imposed on the polymer...
