Abstract

Based on the rheological 1D model the properties of a generalized elastoplastic material are described in this paper. This model is used to analyze the behavior of cable- in-conduit superconductors under cyclic transversal loading. The modification of elastoplastic model is described by introducing the dependence of the elastoplastic properties on the magnitude of the stress. The constitutive equations are explicitly deduced. The parameters of the model are selected according to experimental data. The constructed theoretical diagram illustrates the potentialities of the model.
