Summary: The paper gives a short introduction into classical and non-classical creep models, and presents their applications to structural mechanics calculations. In solid mechanics, two types of equations are generally used – material-independent and material-dependent equations. The latter one should contain relations, which are able to reflect the individual response of the materials to external loadings. One goal in mechanics is to formulate suitable constitutive and, if necessary, evolution equations describing the material behaviour phenomenologically. Such an approach should be adopted for the material behaviour by an identification procedure which allows to find relations between the parameters in equations and experimentally determined characteristics of the material. The first part of the paper is related to these questions.Classical creep equations are insensitive to the kind of loading. They describe, for example, identical behaviour under tension and compression (only the sign of the creep deformations is opposite). Finally, we discuss constitutive equations which are able to reflect differences in the material behaviour with respect to the kind of loading.For the entire collection see [Zbl 0932.00066].
