Good morning,
I'm writing here because I have a problem using the Hashin criterion in abaqus 6.10.
Here after i'll post the card I'm using to define damage initiation and evolution.
Can someone tell me if I'm using it in the correct way?(I'm working with S4R elements)
In the damage evolution I'm using in order the "fiber tensile fracture energy", "fiber compressive fracture energy", "matrix tensile fracture energy", "matrix compression fracture energy".
*Material, name=composito
*Elastic, type=LAMINA
150000., 9080. , 0.32, 5290., 5290., 5290.
*density
1.77e-9
*DAMAGE INITIATION, CRITERION=HASHIN, ALPHA= 0.925
2323.5, 1200.1, 160.2, 199.8, 130.2, 92.3
*DAMAGE EVOLUTION,TYPE=ENERGY, SOFTENING=LINEAR
81.5,106.3,0.2774,0.7879
*DAMAGE STABILIZATION
0.001,0.001,0.001,0.001
As output I'mlooking for damage in elements.
*Output, field, frequency=1
*element output, elset=all
SDEG,HSNFTCRT
*element output, elset=all
SDEG,HSNFCCRT
*element output, elset=all
SDEG,HSNMTCRT
*element output, elset=all
SDEG,HSNMCCRT
*element output, elset=all
DAMAGEFT
*element output, elset=all
DAMAGEFC
*element output, elset=all
DAMAGEMT
*element output, elset=all
DAMAGEMC
Best Regards.
