Stress state of a matrix and an inclusion consisting of a twisted multifilament superconductor with a normally-conducting core in the presence of an interaction of the longitudinal current with a transverse magnetic field

A study is made of the stress state arising in an infinite matrix into which is “potted” a long cylindrical inclusion consisting of a twisted multifilament composite superconductor with a core of normal metal as a result of the interaction of the longitudinal component of the transport current with a uniform external magnetic field. It is shown that the approximation of a homogeneous conductor with average elastic properties can be used to calculate the macroscopic stresses in a NbTi-Cu wire embedded in an epoxy matrix. Zh.
