Abstract
For in situ or ultra-fine multifilamentary Cu-Nb-Sn, the Jc maximum versus strain varies from strain values of 
% for the smallest interfilament spacing to 0.2 - 0.3% for the largest interfilament spacing. Finite element analysis is used to calculate the residual stress (and strain) components from the thermal contraction and to obtain the stress-strain curves following uniaxial loading. The influence of the superconducting volume fraction and the plasticity of the matrix are included in the analysis. One of the most important features is the net reduction of the residual tensile stress on the matrix which occurs when the configuration is changed from a monofilament to multifilament.
