/ANIM/BRICK/DAMA

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.

Comments

  1. If the integration point ijk does not exist in a solid, damage value is set to 0.
  2. 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
  3. The damage value, D is 0 ≤ D ≤ 1. The status for fracture is:
    • Damage occurs, if 0 ≤ D < 1
    • Failure, if D = 1
  4. D is computed for every failure criteria as follows:
    • Strain-based failure (/FAIL/BIQUAD):(1)
      D = Δ ε p ε f
    • Johnson-Cook failure (/FAIL/JOHNSON): (2)
      D = Δ ɛ p ɛ f
    • Cockcroft Latham failure (/FAIL/COCKCROFT):(3)
