A new command for the post-treatment of fracture mechanics
4 October 2012
by S. Géniaut, EDF R&D / AMA
The news command POST_RUPTURE will enrich the possibilities of post-treatment in fracture mechanics. This new command is used in the following of calculation of energy release rate and stress intensity factors (CALC_G or POST_K1_K2_K3).
POST_RUPTURE allows many generic treatments :
- normalization of the curvilinear abscissa,
- calculation of the angle of bifurcation,
- calculation of the equivalent stress intensity factor,
- set to zero the negative values of K1 stress intensity factors
POST_RUPTURE provides also useful operations for fatigue calculations, in addition to existing fatigue calculation commands :
- cycle counting in fatigue,
- cumulation of fatigue cycles,
- calculation of the crack propagation increment due to fatigue,
- continuation method for propagation.
Available in the version 11.0.2 and later
