[5] The general constitutive relations for a material is represented by a fourth order tensor in the form: Oij = Cijklekl i, j, k,1 = 1,3, Symmetric in both i, j and k, l For numerical convenience, the above relation is normally reduced to: 0; = Dijj, i, j = 1,6 , Symmetric in i,j Find the relation between the coefficients Dij and Cijkl for a general anisotropic material.
