Conclusions

  1. 1.

    The strain curves for various states of strain with vε i = const and T=const may be described to a first approximation by a single general curve for the stress σi against the strain εi, with the latter dependent on the temperature and the strain rate.

  2. 2.

    A theoretical description has been given for the biaxial strain curves using nonlinear equations incorporating the volume change.

  3. 3.

    Theoretical calculations have been performed via parameters derived from uniaxial stretching and give satisfactory agreement with experiment for two-dimensional stress over a wide range in the ratios between the components of the principal stresses and also a wide range in strain rate.

  4. 4.

    The generalized strain curves for PTFE are similar, no matter what the state of strain, up to εi = 10% within the range of strain rates examined.
