English abstract:
The paper presents an energy based approach to estimate stress envelopes of composite unit cells exhibiting non-linear mechanisms. Based on non-linear simulations, these damage progression envelopes can be seen as an extension of the well known failure surfaces to cope with damage, plasticity, and delamination. To demonstrate the concept a 2/2 Twill weave featuring damage, plasticity, and softening in the homogenized tows as well as plasticity within the matrix pockets is subjected to biaxial and uniaxial load cases. Multiple non-linear simulations are conducted and the respective damage progression envelopes are constructed for two different energy levels.
