Definitions

Field	Contents	SI Unit Example
`DMGEVOID`	Damage evolution identification number. No default (Integer > 0)
`TYPE`	Damage evolution type. COHDISP Damage index evaluated by displacement. COHENRG Damage index evaluated by energy dissipated. No default
`SHAPE`	Profile shape of the traction-opening curve in the descending part. LIN (Default) Linear shape. EXP Exponential shape.
`MMXFM`	Mode mixed form (only for `TYPE` = COHENRG). Blank (Default) Modes are not mixed. 1 Power law form. 2 Benzeggah-Kenane form.
`ALPHA`	When `TYPE` = COHDISP with `SHAPE` = EXP, it is the exponent for the traction-separation curve. When `TYPE` = COHENRG with `MMXFM` = 1, it is the exponent for the mixing formula. When `TYPE` = COHENRG with `MMXFM` = 2, it is the mixing coefficient. No default (Real > 0)
`W1`. `W2`, `W3`	Material curve parameters. When `TYPE`=COHDISP, only `W1` is required. `W1` The separation evaluated from damage initiation to failure. `W2` and `W3` Must be blank. When `TYPE`=COHENRG, the parameters are the energies that can be dissipated in pure normal and pure shear separation. `W1` Energy dissipated in Mode I. `W2` Energy dissipated in Mode II. `W3` Energy dissipated in Mode III. When `TYPE`=COHENRG with `MMXFM`= Blank. `W1` Energy dissipated. `W2` and `W3` Must be blank. No default (Real > 0)

Comments

The material identification number should be unique for all MAT1, MAT2, MAT3, MAT8, MAT9, MGASK, MCOHE, MCOHED, DMGINI, and DMGEVO entries.
