Conclusions

  1. 1.

    The theory of quasilinear creep equations in the form (3) or (4), which we have presented, is a general theory, since it is free of assumptions concerning the existence of isotropy, incompressibility, and creep potential.

  2. 2.

    The only assumption adopted concerning the existence of creep-curve similarity is generally satisfactory. This is confirmed by the results of experimental investigation and moreover, the effect of similarity can be verified for any time t of the creep process.

  3. 3.

    The method that we have presented for describing creep makes it possible to investigate anisotropy during creep without additional studies.
