This PlugIn computes stress tensor of bonds. The stresses are computed from the
Hook's law. So, the bonds must have a `DEM::BondStrain` property. If you set a
`MaxPrincipalStress` or a `MaxNormalStress` values, this plugin can manage fracture
by disabling the required bonds.
### Info ###
+ Process on : `DEM::Bond` which own `DEM::BondStrain` property
+ Multithreaded : No
+ Recommended section: Processing
### Required param ###
YoungModulus (float)
: Set the Young's modulus for the Hook's law application
PoissonRatio (float)
: Set the Poisson's ratio for the Hook's law application
### Optional param ###
MaxPrincipalStress (float, default=None)
: Set a failure limit in terms of maximal principal stresse values (Rankine criterion)
MaxNormalStress (float, default=None)
: Set a failure limit in terms of maximal normal stresses (normal to the bond facet)
### Example ###
```
<UPDATE-STRAIN Method="LSQ" />
<UPDATE-BOND-STRAIN />
<UPDATE-BOND-STRESS YoungModulus="50e9" PoissonRatio="0.2"/>
