Modelling Crack propagation in a viscoelastic material using cohesive zone modelling in abaqus.

Submitted by Prashanthi on

Hello everyone,

I need to validate crack propagation in a viscoelastic material using Cohesive Zone Modelling. I have given following properties as  fracture criterion. 

Damage initiation= MAXS damage, Normalstress=Shear1=Shear2=3.4MPa.

Damage Propagation:

Type: Energy,

Softening: Exponential

Degradation: Maximum

Mixed mode behaviour: Power Law

Mode mix ratio: Energy

Power:1

Fracture energy(Normal)=Shear1=Shear2=274J/m2.
