Getting from Strain Energy to Strain
Getting from Strain Energy to Strain
(OP)
New FEA guy using SDRC I-DEAS. Under display defaults are Displacement, Stress, and Strain Energy. How do you get from Strain Energy to Strain. I know strain energy is Nm (J) and strain is unitless. Not sure what I'm missing.





RE: Getting from Strain Energy to Strain
Not sure what I-DEAS is putting out but in general strain energy is 1/2 summation( stress * strain)....for all components of stress and strain....
Hope that helps...

In IDEAS strain is not a default output. You can output strain by going to
Model solution
Examine /Modify
Output selections
Hilite Strain
Store
Ok
Solve again
Of course you should selete ur results first.
