I run simulation use material from NCell 40 : GreenCore Composites. Unfortunately, results for in cavity residual stresses first principle not exist in Flow Results
Then, when i run with other material from ISOFORM LIP CPCW 50 : ISOKON, results for in cavity residual stresses first principle exist in Flow Results.
Do you think this problem because udb.file? Hopefully technical support for material database will be help me to solve this problem as soon as possible.
Please refer the attachment file, why in mechanical properties for ISOFORM LIP CPCW 50 : ISOKON write with red compared with NCell 40 : GreenCore Composites write with black. Do you think udb.file for NCell 40 : GreenCore Composites have problem?
Solved! Go to Solution.
In-cavity residual stress result is not generated if the Residual Strain shrinkage model is selected for the material used in the analysis.
View the material properties data for the specified material on the Thermoplastics material dialog
(Select Material > Details > Shrinkage Properties tab).
NCell 40 : GreenCore Composites
In material Shrinkage Properties, it has Residual Strain shrinkage model, therefore no In-cavity residual stress result(It has shrinkage test data.)
ISOFORM LIP CPCW 50 : ISOKON
In material Shrinkage Properties, it has Uncorrected residual stress, therefore In-cavity residual stress result available
(It has no shrinkage test data.)
You can change the shrinkage model used for NCell 40 : GreenCore Composites, to get In-cavity residual stress result, but be careful and aware of that the change of shrinkage model affects the Warp result.
In Process Settings, Advanced Options...
Molding Material : Edit...
Shrinkage Properties tab
Select a shrinkage model : change to Corrected residual in-mold stress (CRIMS) or Uncorrected residual stress
