Summary of results ====================== The results found in terms of elastic energy with *Code_Aster* are very satisfactory in small deformations and in logarithmic deformations, with analytic deviations of less than 0.1%, and correct in deformation of SIMO_MIEHE, with an analytical difference of about 3%, with an analytical difference of about 3%, due to the term :math:`\mathit{tr}(\stackrel{ˉ}{{b}^{e}})`, on which the fifth decimal plays a significant role.
