Abstract: | Multiaxial stress-strain damage relations, describing both time-independent and time-dependent strain and damage creation are postulated. The influence of damage creation on the load carrying capacity of simple structures is discussed. The time-independent deformation, and loss of stability, of a thick-walled cylinder under torque and internal pressure are analysed. The results are shown to be similar to previously found results for a beam under tension and bending. |
