“…when the state of damage is represented by a tensorial variable. The modeling of damage anisotropy can be made by use of microplanes models [8,9,10] or by use of a fourth [30,31] or now more commonly of a second order damage tensor [13,14,38,16,59,17,20,21,18,23,25,26,24]. The key point of a thermodynamics consistent modelling is to ensure the positivity of the intrinsic dissipation and in particular the positivity of the dissipation due to damage [39,40,27].…”
