Summary

This materials science study develops three-dimensional finite-element models for Rutherford-type superconducting cables by characterising the mechanical behaviour of individual strand components. Using experimental tensile testing and microstructural characterisation of Nb₃Sn strands, the authors identified behaviour laws for copper (modelled with non-linear elastic-plastic constitutive relations) and the superconducting filament composite (via numerical homogenisation). The validated strand model advances the capability to predict performance under the complex loading conditions experienced by high-field magnet conductors.

UK applicability

This research is not directly applicable to UK agricultural, soil health, or nutrient density contexts. The record appears to have been catalogued in error, as it concerns materials engineering for superconducting magnets rather than farming systems or human nutrition.

Key measures

Mechanical behaviour parameters (elastic-plastic properties, isotropic and kinematic hardening coefficients); strain response under axial and transverse loads; finite-element model validation against tensile test data

Outcomes reported

The study identified and validated representative behaviour laws for different components of Nb₃Sn superconducting strands, including non-linear elastic-plastic copper behaviour and homogenised superconducting filament properties. The strand model was compared against both monotonic and cyclic tensile test data on powder-in-tube manufactured Nb₃Sn strands.
