Ahstraet-We have derived the expression of the damage factor, D = 1 -(G/G), by applying Lemaitre's strain equivalent hypothesis to the pure shear case, and used it as the theoretical basis for measuring D with the thin-walled cylinder torsion test. According to the damage strain energy release rate
