    2. Unlimited isotropic solid. Potentials

    In this case, according to relation 94 of [AF 3 812] , the relation (3) is written :

    T ij = λSδ ij + 2µS ij . ( 4 )

    The two independent coefficients λ and µ (expressed in GPa) are referred to here as Lamé constants. This pair of constants characterizing the isotropy of the material can be replaced by another: Young's modulus (Y )...
