Requirment of input data for FEM analysis in ABAQUS and high resolution contour plot

[abc123ali]

Resepecetd ABAQUS Users, I am simulating a model for adhesion of two plates with a binder or adhesive in between them for which I input shear stress - strain data. Is it possible to perform tensile, bending tests using the same data? or may I need to do experimental work again and input new data for tensile and bending tests? Is there an option to export high resolution contour plot from results?
Thanks for cooperation

How do you model the adhesive ? Which material model available in Abaqus are you using ?

There is a File —> Print option that you can use to save the content of the viewport.

I am using yield stress-strain data in property module to input pasticity isotropic model and elastic properties for binder.

Ok, I thought that you are using something like cohesive elements or surfaces (contact) to model the adhesive. But if it's just *PLASTIC then you should use data from a tensile test and this model can be utilized regardless of the type of loading.

You mean that I can use the data from either of the tensile, shear or bending test and no need to perform all the tests experimentally and then I can perform other two tests based on data of anyone of these. I am using this binder using tie constraint in the interaction module. So is it fine?
Thanks

It should be tensile data as input and then the plasticity definition is universal - can be used for any type of loading (including e.g. shear test of the connection).

Yes, tie constraint is usually sufficient in such cases.

I disagree.
Adhesive shear stress-strain data for a bonded joint (using metal adherends) should come from a shear test such as ASTM D5656, not from a tensile test.
What "tensile" or "bending" tests are you referring to?

Would be very helpful if you would post pictures of the actual joint you are modelling, and of the actual test specimens you want to use.

How specifically are you modelling the adhesive? what element types? show a picture of the FEM.

 

[FEA way]

And you would enter it as regular plasticity data ? That’s what the OP is currently doing. If he was using a more complex approach such as cohesive elements or surfaces then the data should indeed come from more specialized tests. But with such a simplified approach, regular plasticity should be defined in a standard way.

if you have a data , you can plot it in Python to generate EPS format very easily with desired resolution, you can also ask ChatGPT if you don't do it by yourself.
