Abstract
The present contribution aims in providing a gradient extension of Gurson's model which combines computational efficiency with a sound micromechanical basis. For this purpose a theory of homogenization towards unconstrained microdilatational media is developed. Based on this theory, a limit-load analysis is performed for a unit cell with void leading to a closed-form yield function of Gurson-type which contains additional terms of the microdilatational theory.
