Abstract

The critical state stability in non-uniform superconducting composites is investigated, taking into account the plastic yield of the material. It is shown that the critical state instability in the non-uniform region may occur considerably earlier than in the uniform part of the sample. The instability criteria have been obtained for a number of particular cases. The training phenomenon in superconducting composites is discussed as a sequence of local magnetic flux jumps and plastic strain jerks developing simultaneously.
