A Warp analysis is used to diagnose the cause of warping and recommend a solution, such as gate location changes, design parameter changes, or reduction of wall thickness variations.
Warp analysis is supported for Mid-plane, Dual Domain and 3D analysis technologies.
Warpage is affected greatly by fiber orientation. Warpage in an injection molded part is caused by variations in shrinkage that occur:
- From region to region in the part.
- Through the thickness of the part.
- Parallel and perpendicular to the direction of material orientation.
Any attempt to predict the likelihood and amount of warpage for a particular component must first account for these shrinkage variations.
The material that is used influences the warpage of the part. Sometimes you must choose a material with low, uniform shrinkage to achieve dimensional accuracy. These materials are usually more expensive, but you may be able to use a cheaper material and save costs by observing shrinkage and warpage design principles.
Note: Differential shrinkage caused by fiber orientation is one of the main causes of warpage.
If you are analyzing a fiber-filled material you should turn on the Fiber analysis option in the Fill+Pack process settings.
Warp analysis types
There are different warp analysis types that can be selected.
The following Warp analysis types are available and can be selected from the Process Settings Wizard:
Buckling
Determines whether the warpage of the part is stable or unstable.
If the buckling analysis indicates that the warpage is stable (critical load factor > 1), the deflection results obtained from the buckling analysis provide a good indication of the final deformed shape of the part.
If the buckling analysis indicates that the warpage is unstable (critical load factor < 1), you will need to run a large deflection analysis to determine the final deformed shape of the part.
This analysis is performed on Midplane meshed models.
Small deflection
Select this analysis type if you expect the warpage of the part to be stable. The small deflection analysis provides the final deformed shape of the part, assuming linear stress-strain behavior within the part.
This analysis can be performed on Midplane, Dual Domain and 3D meshed models.
Large deflection
Select this analysis type if you expect the warpage of the part to be unstable, as determined from a previous automatic or buckling analysis, or the warpage of the part is borderline stable/unstable and/or you want the most accurate prediction of the shape of the part. The large deflection analysis provides the final deformed shape of the part, allowing for nonlinear stress-strain behavior within the part.
This analysis can be performed on Midplane and 3D meshed models.
Automatic
Select this option if you want the solver to identify whether the warpage is stable or unstable. If the warpage is determined to be unstable and you are using a Midplane mesh, this option will automatically run an additional large deflection analysis to determine the true final deformed shape of the part. Depending on your mesh type, automatic analysis first runs a buckling analysis, a large deflection analysis is run if the Eigenvalue is less than 1.5, otherwise a small deflection analysis is performed.
The Warp analysis uses the results of the Cool analysis and the Fill analysis to predict shrinkage and warpage of the part. Modeling tasks and an analysis sequence must be set up before a Warp analysis is run.
