Hi,
i am a novice ABAQUS user , i have a Rechtangular 3D Model (elastic Plastic) of 4 hexagonal grains with different Poisson's Ratio and Modulus of Elasticitis,the target is cohesive zone model (Traction-Separation Law) ,Mode I
for the cohesive zone i created the contact interactions, Mechanical --> Tangential behavior, surface to surface contact (standart ) as the type and initial as the step.
hier are my input parameters :
1. I inserted Yield strength ,and 0.2% plastic strain , in Edit Material dialog box for each grain as parameter :for exampel grain Nr.1 has the parameters :
Yield strength plastic strain
400 0
500 0.002
butt i don't know it's correct or not ????
2. I used a cohesive surface interaction and I set the cohesive behavior and damage properties :
*Cohesive Behavior
8.43e8, 8.43e8, 8.43e8
*Damage initiation, criterion=QUADS
175., 175., 175.
*Damage Evolution, type=ENERGY, mixed mode behavior=BK, power=2.284
0.1,0.1,0.1
*Damage Stabilization
1e-05
*Friction
0.0,
when i run i get these error :
Please can any one help me in that and thank you in advanced.
