Pure shinkage

[subpartner]

1. Is there any way to create a plot to show pure shrinakge of a part?

2. How can I seperate the value in the plot of "DEFL W" in X, Y, Z?

1. In Midplane and Dual Domain analysis there are four shrinkage related plots: "Isotropic shrinkage", "Anisotropic shrinkage", "Parallel shrinkage, before warpage" and "Perpendicular shrinkage, before warpage".. In true 3D analysis, I guess the best way to get the linear shrinkage plot is divide the volumetric shrinkage by 3.0

2. In deflection plot properties. Choose the needed component instead of the magnitude:

Hi Alex,

Anyway thanks a lot for you help. I know what you said, but what customer want to know is the "Pure shrinkage" in a specified direction. The parallel and perpendicular is changed with orientation, and deflection already include warpage...

I guess I could write a simple script that would produce the result.

Is the analysis midplane, dual-domain or 3D? Is the part flat or we need some type of projecting the shrinkage direction on the curved surface?

Might be better to raise that through normal support channel ?

Hi,

Yes current workaround is as follows:
You need to select 2 co-ordinate points on part in a Deflection result. Selecting 2 points will not be equal to interpreting about direction, so difficult to say about parallel & perpendicular shrinkage values.

In the attached image you will need to select Co-ordinate+Shrinkage instead of if Autodesk may provide one more option "Pure Shrinkage/Only Shrinkage" in the dropdown will be great. This could be a New Idea.

In warp results

Check shrinkage compensation & automatic. You will get estimated shrinakge rate

Better to do Shrink analysis

Shrink analysis enables you to determine an appropriate shrinkage allowance to use to cut the mold taking into account the shrinkage characteristics of the material being used to mold the part

and the molding conditions.It helps in Calculation of a recommended shrinkage allowance.
