Cohesive zone method
CZM

Dear all,

I want to define cohesive surface in my model which is a polycrystalline of Titanium with its grains. Can anyone help me that How I should find the appropriate values for fracture energy and mode mix ratio 1 and 2?

For damage initiation, what do I consider for normal, shear 1 and shear 2 in contact property of interaction module? Are Tensile and shear strength suitable for these properties?

Thank you

What are the boundary conditions of an elastic rod at a clamp moving on a perfectly smooth and rigid circular profile?

The tangential shear at the clamp turns out to not be null!

Finding element number corresponding to Fastener in a set in Abaqus

fastener

Hi,
I have a model in which I used fasteners to find bolt forces. I created fastener sets and requested output by changing Domain to "Fastener" and selecting the set that contains Fasteners.
The problem now is, I'm not sure which force corresponds to particular bolt.


Options>Common>show Labels for elements only shows element numbers of remaining model but not Fasteners.
