| This model was based on stress triaxiality, which is defined as the ratio of the hydrostatic stress to the equivalent stress. |
|
| From figure 12, it is clear that bulging induces triaxiality to a test that is supposed to capture rubber uniaxial stresses and strains. |
|
| Some preliminary investigation of the stress triaxiality factors is also presented. |
|
| Others new hypothesis and equations are introduced by the use of FEM studies, in particular, stresses and forces distributions, triaxiality close to the tip of the tool. |
|
| The article also includes results of the notch effect on a stress triaxiality under the elastic stress state with the evolution to the increasing elastic-plastic deformation. |
|
| Triaxiality of stress experienced by the elastomeric matrix confined within the filler particles increases. |
