The mechanical properties of a superconducting composite cylinder with transport
current are investigated. By adopting the exponent model, the nonlinear differential equations for
flux distributions are derived. The elastic solutions to stress, displacement and magnetostriction
are analytically given. Some typical numerical results are displayed. Numerical results show that
in the process of transport current reduction, tensile stress generally occurs in the outer region
of the composite, and that displacement is always negative in the composite. In addition, as the
applied maximal transport current exceeds the outer-cylinder critical current, a hysteresis loop
of the magnetostriction exists for the full cycle of the transport current.
