11 Relation between the two damage variables in the case of elastic energy equivalence (Reprinted with permission from Voyiadjis and Kattan 2012) Table 2 Limiting values of f2 and ‘2 (Reprinted with permission from Voyiadjis and Kattan 2012) ‘2 ϕ2 Min. value Max. value Min. value Max. 414 cross-sectional area similar to ϕ1. The second category consists of all the damage variables that are defined in terms of the elastic stiffness similar to ‘1. Other Proposed New Damage Variables Damage Variables Defined in Terms of Area Looking at the damage variable ϕ1 as defined in Eq.
Two such tensors are proposed in this case as shown in Eqs. 81a and 81b. The definition of the alternative damage variables of Eqs. 81a and 81b may be rewritten in the following more appropriate form: ð1Þ Eijkl ¼ δim δjn þ Lijmn Emnkl (82a) ð2Þ Eijkl ¼ Eijmn δmk δnl þ Lmnkl (82b) Hypothesis of Elastic Strain Equivalence Making use of the hypothesis of elastic strain equivalence, one assumes ϵ ij ¼ ϵ ij (83) Using the elastic constitutive relations in both configurations as follows σij ¼ Eijkl ϵ kl (84) σij ¼ Eijkl ϵ kl (85) and substituting for σ and ε using Eqs.
3. The anisotropic damage tensor R is given by À Á À1 Rijkl ¼ Eijmn Emnpq À Eijmn Emnpq Epqrs EÀ1 rskl (103) Equation 103 may be rewritten in the following form: Rijkl Eklrs Erspq ¼ Eijmn Emnpq À Eijmn Emnpq (104) Substituting Eq. 86 into Eq. 104 and simplifying the terms, the following equation is derived: Rijkl ¼ Mijkl À β δik δjl (105a) Equation 105a represents the anisotropic damage tensor based on the hypothesis of elastic strain equivalence. It can be verified that the damage tensor R is valid for values of R1111 greater than zero.
