Engine Keyword Generates animation files containing
damage value as function of a solid element integration point. The damage value is the
maximum of damage over time and of all failure criteria acting in one material.

Integration Point Number:
- 0 or blank
- Maximum integration point value in the element is
output.
- i, j,
k
- Value in integration Point of brick element.
- i
- Integration point number in direction r.
- j
- Integration point number in direction s.
- k
- Integration point number in direction t.

Comments
- If the integration point
ijk does not exist in a solid, damage value is set to 0.
- If j is
greater than or equal to 10 (in case of /PROP/TYPE22 (TSH_COMP)),
syntax becomes:
- /ANIM/BRICK/DAMA/i0k/j
- With 10 ≤ j ≤ 200
- The damage value,
D is 0 ≤ D ≤ 1. The status for fracture is:
- Damage occurs, if 0 ≤ D < 1
- Failure, if D = 1
- D is computed for every failure criteria as
follows:
- Strain-based failure (/FAIL/BIQUAD):(1)
- Johnson-Cook failure (/FAIL/JOHNSON):
(2)
- Cockcroft Latham failure (/FAIL/COCKCROFT):(3)
- Tuler-Butcher failure (/FAIL/TBUTCHER):
(4)
- Wilkins failure (/FAIL/WILKINS):
(5)
- BAO-XUE-Wierzbicki failure (/FAIL/WIERZBICKI):
(6)
- Strain failure model (/FAIL/TENSSTRAIN):
(7)
- Energy density failure model (/FAIL/ENERGY):
(8)
- Hashin Composite failure (/FAIL/HASHIN) - the maximum
damage for different failure mode:
- for uni-directional lamina mode(9)
- for fabric lamina model(10)
- Puck Composite failure (/FAIL/PUCK) - the maximum
damage for different failure mode: (11)
- Ladeveze failure (/FAIL/LAD_DAMA)(12)
- Strain Failure Model with dependence on Lode angle (/FAIL/TAB1) (13)
- Spalling and Johnson-Cook failure (/FAIL/SPALLING):
(14)
- Ladveze composite failure (/FAIL/LAD_DAMA):
(15)
- Failure According (Normal and Tangential) Displacement Criteria and/or
Energy Criteria (/FAIL/CONNECT):
(16)
- Failure According Plastic Displacement Criteria (/FAIL/SNCONNECT):
(17)
- Extended Mohr Coulomb failure model (/FAIL/EMC):(18)
