Creo Simulate - question is on the Result Type - Strain Energy per unit volume

[GS_8530322]

Hi,

My question is on the Result Type - Strain Energy per unit volume

1. After running a Modal Analysis, Strain Energy per Volume can be viewed either  by Graph or by Fringe. What is the difference between them

2. Under the Graph - Strain Energy per volume and selecting a curve, is this the  strain energy of the unit volume or of the the curve ie an edge of the assembly.

Hi,

By Fringe you can view the result overall on the complete model or selected models.

By Graph you can XY Plot the result, as in your case Strain energy per volume versus Curve/Path or Co-ordinate(X,Y or Z) you select. Selecting a curve means choosing a path on which you want to identify the result. That path can be edge/sketch/curve on model, provided it is on affected surface where result is calculated.

So, fundamental difference between Fringe and Graph is former is for 3D result visualization and latter one is for result representation in form of 2D Graph.

2D Graphs results are mostly used when you are doing some geometrical R&D. For example : if you want to know what is the exact 

Whereas for final validation of the design Fringe is the most appropriate for result interpretation.

Thank you,

Further, the Analysis model is an assembly of parts connected with fasteners in Simulate and modal analysis is done.

Now, by selecting the Graph-Strain Energy Result to an edge of a part, does the graph shows the Strain Energy per volume of the single part or of the assembly.

The measure is Strain Energy per UNIT volume.

The simplest way to describe this is that the strain energy per unit volume is an element level result:. SE in the element divided by volume of the element. The fringe plot and the graphs along curves are showing the exact same result, it is just a matter of the location you are querying. This measure is a way to normalize the strain energy independent of the size of the element. Larger elements have more strain energy for the same strain, just because they are larger. A note on modal analysis. There is no load or input actually applied so the whole result has been normalized for example so the maximum displacement is 1, or by overall mass of the assembly. There is a config. option for this. What this means to me is that the results are really only comparable within the same model for what part of the model is doing more work in a particular mode shape. The dynamic analysis options with the advanced simulate license will allow putting inputs into the modal analysis and getting actual stress/strain levels and displacements, etc.

Is there something you are trying to find out about your model that the community can help with?

Thank you , that explains the requirement.
