摘要：

The elastic constants of the fluxoid lattice are calculated in terms of the reversible magnetisation curve by taking the appropriate derivatives of the free energy of the fluxoid assembly. The expressions obtained in previous work for the compressional modulus and for the shear modulus c44 in magnetic fields well below Hc2 are confirmed and their validity over the entire range of field between Hc1 and Hc2 is established. A new expression is derived for the shear modulus c66 in high fields. It turns out that c66 goes quadratically to zero if the applied field approaches Hc2.
