5. Summary of results

The test case allows a comparison of the results obtained from a thermal load and a field of initial constraints. It shows that the results are substantially equivalent.

More precisely in FEM (modeling A):

• Conclusions on G:

  • Excellent independence of the results of CALC_G at the crowns (maximum difference between crowns less than 0.004%), in all cases,

  • Strictly identical results between an initial constraint field provided to CALC_Gde type ELGAet ELNO,

  • Results very similar to the reference, with the same crown (difference less than 0.01%). The closest results are obtained when the initial stress is given to the nodes at CALC_G,

• Conclusions about K:

  • Same conclusions as on G, with double precision each time (maximum difference between crowns less than 0.002% and reference difference less than 0.005%)

It should be added that this same case gives the same results with the Abaqus software in its version 6.11 (method FEM, calculation of G only).
