WebMar 5, 2015 · Viewed 4k times. 8. In linear elasticity theory the stress tensor σ is related to the strain tensor ϵ via the elastic tensor C. Specifically. σij = Cijklϵkl. Because σ and ϵ are both symmetric second rank tensors, σij = σji and ϵkl = ϵlk so that C has the so-called "minor symmetries": Cijkl = Cjikl = Cijlk. WebMaxwell’s reciprocal theorem [19] states that two strains must be equal if the two stresses are of equal magnitude and sense. It is implicit in the symmetry of the stiffness/compliance matrices for a square symmetric material (E 2 = E 3) that ν 12 E 2 = ν 21 E 1, and hence ν 12 = ν 13, ν 21 = ν 31 and ν 23 = ν 32.
