Hi John,
1) I would recommend creating a coupling constraint between a master node and all the nodes along the face of the unit cell and apply a concentrated force to the master node.
2) Yes
If your results are not matching, you may want to adjust fiber/matrix properties.

Hi Qwerty,
1) Engineering constants will work for your model.
E1 = 23000
E2 = E3 = 8500
v12 = v13 = 0.23
v23 = 0.5 (typical value for GRP)
G12 = G13 = 3000
G23 = E22/[2(1+v23)] = 2830
2) In the property module, you will need to assign a material orientation. I find it most useful to create...
Hi MB,
There is a webinar March 22/24 that discusses new cohesive element modeling solutions for composite materials. I don't know if you are modeling composites but the webinar would be informational regardless.

Hi abaqus007,
You may have to use an additional product that calculates cycles to failure for a particular stress field determined from an Abaqus analysis. FeSafe works with Abaqus output databases to provide fatigue analyses.

Hi Odforu,
Making the surface rigid is one option. What you constrain by doing this is the ability for the material to Poisson. You may want to choose a kinematic coupling constraint or equation constraint instead.

Hi clint05,
There are multiple cohesive element types in ANSYS that employ a traction-separation relationship to model adhesive failure. I would focus on using the INTER205 element.

Hi Odforu,
You want to specify the field output variable TSAIW to be available for post-processing. You also want to make sure to specify output data to be saved at multiple section points as by default only the top and bottom section points of a layup are saved.
As an aside, I have had more...
