How to determine strain history of part?

Autumn

Hi,

I am trying to determine the strain history of a part - either maximum strain or maximum plastic strain over the run time - but can't seem to figure out how to go about plotting such a thing. I understand it is possible to contour plot the plastic strain of 3D elements in HyperView, and that I could then plot this vs time for a specific element(s), but is there any way to just plot the maximum of all elements (I'm not really concerned with which element this maximum occurs if this makes it easier)?

Is it possible to do in either HyperView/HyperGraph or HyperStudy? Or perhaps using Compose is the best way (I am not very familiar with this program yet)?

(I am looking specifically at 3D elements and am using Radioss).

Please let me know if you require any clarification.

Thank you in advance for any tips and help you can provide.

hi,

 

you can get this easily in HV+HG.

Plot your results for strain in HV.

Activate the 'measure' panel, and activate the 'dynamic measure' and choosing only 'max' value (turn of any other).

Then go to 'Create curves' in the measure panel, and create a new curve with 'live link' enable.

This will create a new HG window with your maixumum over time.

What about using BCElemToPart and which will aggregate all values >> you will ask for max

once the data is there as new results you can use standard measure for each part and plot the curve in HG.

Adriano,

 

FYI: The approach of dynamic legend is valid for global maxima. 

Leveraging part aggregation would allow as well the screening for each part.

 

That being said, the approach thru measure is valid at the end for both methods.

Thanks

good point, Michele.

Using result math is a really nice approach.

 

for the dynamic measure to work for a particular part only, it is necessary to select and contour only this particular part.

Autumn

Thank you both for these suggestions!

I ended up contouring only the one part of interest in HV and utilized the dynamic measure to create the HG curve.

Hello Automn,

in our latest 2021.1 version, HyperStudy allows a new model HyperView.

This model allows to create some metrics with the HotSpot Finder in HyperWorks View (HyperView with the new interface). The results can be stress, strain,... and you can control the selection of elements.

Eg you can remove from element selection the first raw of elements connected to rigid elements when post-processing stress results.

You can set up as much metrics as you want (one per Window), save your HotSpot Finder settings for each window wit a relevant name, then save your session file.

Then, once back in HyperStudy, define a HyperView model and call the mvw file. Also, make sure to link the output file from your first model to the HyperView model.

We'll post soon an article in the Knowledge Base an article regarding this new model, with extra details. I'll post the link t this article in this page when available.

Best Regards,

Michael

This information is good to know! I look forward to the article in the Knowledge Base.

Thank you!
