Notch Stress Configuration dialog box

Name-Description
Name	Sets a unique name for the parameter.
Label	Sets a unique integer for the parameter.The dialog box automatically displays the next available label number. However, you might want to change this if you use a particular series of numbers to identify certain types of parameters.
Description	Sets a description for the parameter.This description appears in the Durability Simulation Objects dialog box only if you add the Description column to the list table. To do that, right-click the column heading row and choose Columns→Configure. In the Configure Columns dialog box, select the Description check box and then click OK.
Categorization
Category	Sets the category name for this parameter.
Sub-Category	Sets the subcategory name for this parameter.The subcategory appears in the Durability Simulation Objects dialog box only if you add the Sub-Category column to the list table.
Properties
Notch Model	Specifies the method to use to take into account variations in the seam weld geometry.R1MSUses a weld radius of 1 mm.This method was developed for sheet thicknesses between 8 and 40 mm.R03MSUses a weld radius of 0.3 mm.This method is intended for sheet thicknesses between 2 and 20 mm.R005MSUses a weld radius of 0.05 mm.This method is intended for sheet thicknesses between 0.5 and 2.0 mm.For more information, see The R1MS approach and R03MS and R005MS approaches.
Automatic Scaling	Applies size scaling to the seam weld matrix.When you select this check box, the fine model is scaled to have the exact thickness of the actual sheets. The algorithm then uses a different radius for the notches. For example, suppose a seam weld matrix is calculated for a base sheet thickness of 2 mm and the optimal base sheet thickness is 3 mm. The scale factor would be 1.5.If you clear this check box, only seam weld models that reflect the selected radius (R1MS, R03MS, or R005MS) are used. If the thickness of the sheets in the actual model does not correspond to one of the fine models, the next conservative model is used.
Geometry Definition	Specifies the type of geometry used between connected sheets.Changing AngleApplies the best fine model at each node.Best FitSelects the optimum geometry automatically based on the selected weld type.User DefinedLets you specify the model class.
Seam Weld Model	Appears when Geometry Definition is set to User Defined.Sets the class of models from which an appropriate one is selected.This name describes the seam weld type and the angle of the sheets, such as Y_0_90_180.
Relative Averaging Length	Specifies the length for averaging the forces and stresses.This normally applies if the elements are very small along the welding (< 3-5 * element thickness). In this case, the specified value is multiplied by the element thickness (thus it is relative) and, using this new length, the values of the elements are averaged.If you set this value to 0, no averaging takes place. This can be changed in each seam weld instance afterward.
Scale Factor for Seam Weld Ends	Sets a scale factor for the forces at the seam weld ends only.
