DIRECTIONS OF COMPOSITE STRESS VISUALISATION

Recommended Posts

Hello everybody,

 

I am currently simulating a 4 Point Bending Test on a rectangular Sandwich Panel. I'd like to prove Navier's linear strain distribution with it.

My question is: when I visualise the Composite Strains (or Stresses) in Normal X or Y directions, which coordinate system do these directions refer to: the global one (1 in the picture I attach), the elemental one or the material one (2)?

I have plies at 0º and 45º orientations and I wonder whether I can compare the results for each of them straightaway by checking the Normal X Strain in each ply, or otherwise I need to apply some kind of rotation to do so.

 

Thank you very much,

 

Carlos

Hi carlosmarbo,

 

Plies will be oriented with respect to material system. But, make sure while creating the plies you select the material system every time you create a ply.

Ok Premanand,

I have ensured that the material orientation of each ply is properly set. However, the results are still the same as in the picture I attached. I would say that, in a 4 Point Bending Test, the strain in the Global X Direction should be something like in the following image, which is what I get for the 0º plies:

That is why I am not completely sure I'm seeing the results in the direction I want (Global X) or in Material X (which is rotated 45º from Global X).

Thank you very much,

Carlos

According to Hyperview help, for Abaqus template it is not possible to plot results in "Material system".

 

However, you can import the model, with the coordinate systems, together with the results and then use the "User system" option.
