Fracture using cohesive elements

Submitted by yashaswi.prateek on

Hi everyone , 

I'm Yashaswi Prateek  doing by final year project on fracture in composites using ABAQUS. I'm new to ABAQUS and have been trying to do some tutorials to get a better understanding of the software. After basic tutorials , i've started trying to generate a model using cohesive elements where i got stuck up. I have tried the procedure in Abaqus user manual and is showing some errors regarding interaction properties and creating a step.  It would be great help if someone could help me regarding how to model with cohesive elements.

The model which i have tried consists of top and bottom ( anti - symmetric ) parts with an opening. i want to model cohesive elements between the parts. if someone could hep me with how to generate this model it would be of great help.

 

Regards,
