RE: Weld line strength factor
-
Do you have a list of materials where the PVT (Pressure-Volume-Temperature) and VE (Viscoelastic) properties are characterized with a model that allows for the display of weld line strength factor results?
-
If I run a simulation with one of these materials and obtain values of strength reduction, can these values be automatically used in the stress solver, or will the standard values remain?
- If the material has any one of the models listed below (in the sequence of solver priority used by the weld line strength solver in the filling result), there will be a weld line strength factor result in the filling result.
Unfortunately, we don’t have a list, but for most of the materials recently added to the material bank, we used the Modified Cross Model (3) for viscosity. A few of them with GF will use the Herschel-Bulkley Cross Model (3). For the A and B models for viscoelasticity, our material team didn’t provide any fitting and testing. These two models can only be used if the customer has the parameters of the model. I would like to add that in 2025, we will include the Modified Cross Model (2) (used for most of the older materials in our material bank) to also support weld line strength factor calculation.
- The weld line strength option in the computation stress tab considers only the weld line angle and the remaining strength percentage you set. The strength reduction is based on the Young’s modulus reduction by the percentage you set.
