Ordinarily, stress-strain relation of Lagrange’s representation is written in terms of Lagrange’s representation of stress σij and the Love measure eijL. From the above relation, we can derive Reiner’s equation in terms of Euler’s representation of stress Tλμ and the Green measure eλμG.
In this paper, it is shown the σ′ij and eij defined by
σ′ij=Dx,i*λx,j*μTλμ,eij=\frac12(δij−gij)
can play the role of σij and eijL and starting from stress-strain relation of σ′ij and eij we arrive at Reiner’s equation in terms of Tλμ and the Almansi measure eAλμ.
Various relations relating to four measures above mentioned and to their first variations are also shown, as well as various relations among different strain invariants.
