However, the commonly used variable damage D was replaced with the void volume fraction f , which has a clear physical meaning, and the elastic strain tensor \Bold {ε}^e with the damage-elastic strain tensor \Bold {ε}^{de}. The postulate of strain equivalence with the effective stress concept was reformulated and applied to a case where the response of the matrix obeys Hooke’s law. In contrast to many other studies, in the derived relation between the effective stress tensor \Bold {\Tilde{σ } and the stress tensor \Bold {σ}, the tensor \Bold {\Tilde{σ } is symmetric. A uniaxial bar model was introduce for clarifying the derived results. Other candidates for damage were demonstrated by studying the effect of carbide coarsening on creep rate.</p>}, number={3}, journal={Rakenteiden Mekaniikka}, author={Santaoja, Kari Juhani}, year={2019}, month={elo}, pages={125-147} }
