- The output location in
Keyword4 and Keyword5 can be defined
via:
- NPT
- Integration points.
- LAYER
- Composite shell layer when using /PROP/TYPE11 (SH_SANDW), /PROP/TYPE10 (SH_COMP).
- PLY
- Composite shell ply when using, /PROP/TYPE19 (PLY) or /PLY.
- MEMB
- Generalized membrane stresses per element. Cannot be used with NPT, LAYER or PLY options.
- BEND
- Generalized bending stresses per element. Cannot be used with NPT, LAYER or PLY options.
- Output can be requested for a specific location number (I), ALL, and in some case UPPER or LOWER. The output locations are separated by a / and can be in any order.
- The values of FLD damage factor
is equal to the ratio of the actual major principal strain value over the
forming limit curve value:
(1) Where, is the major principal strain at failure limit from FLD diagram (fct_ID in /FAIL/FLD).
The FLD compares the and using the same .FLDF may be greater than 1, if the option /FAIL/FLD, Ifail_sh=4 is used. In this case, the damage factor is only calculated for post-processing and no elements are deleted.
- The values of FLD zone index are
defined as:
- FLDZ=6
- Failure
- FLDZ=5
- Marginal
- FLDZ=4
- Safe
- FLDZ=3
- Compression
- FLDZ=2
- High wrinkle
- FLDZ=1
- Loose metal
Where,- fct_ID
- Defined in /FAIL/FLD
- Major strain as a limit from FLD diagram from fct_ID in /FAIL/FLD
- and
- The minimum and maximum principal strains
- Rani
- Average anisotropy factor defined in FLD input in /FAIL/FLD
- Defined in FLD input in /FAIL/FLD
- Defined in FLD input in /FAIL/FLD
(2) - I_marg
- Defined in FLD input in /FAIL/FLD
- Option DAMG is
only used with coupled damage models (/MAT/LAW72 or
/FAIL/GURSON) to output damage over integration points.
The damage variable is normalized by its critical value.
- For /MAT/LAW72
(5) - For /FAIL/GURSON
(6)
- For /MAT/LAW72
- When using global integration (N=0 in the shell property), Radioss always outputs the stress and strain only in the midplane (MEMB).
- If /NONLOCAL/MAT option is activated, it is possible to output the regularized non-local plastic strain and its rate.
- The damage initiation variable /H3D/SHELL/DAMINI is used with some failure criteria such as /FAIL/INIEVO, which first computes a damage initiation criterion before computing the stress softening damage variable, which can be plotted with /H3D/SHELL/DAMA.
