摘要：

A test campaign was launched to determine the mechanical properties of the High Luminosity-Large Hadron Collider (HL-LHC) 11 T Nb3Sn magnet components. The results can be used to accurately represent the mechanical properties in finite element models that predict the stress and strain distribution in these magnets. Particular attention is paid to anisotropic mechanical behavior of the different magnet materials. Static and dynamic test methods have been applied for determining elastic materials' behavior, and highly accurate Young's moduli are obtained with the nondestructive dynamic methods resonance and impulse excitation at ambient temperature and during in situ heat cycles.
