In the stress configuration, you can select the stresses to be calculated. You can open the stress configuration in the Navigator – Data using the Stresses entry.
Main
The Main tab manages the list of stresses to be calculated.
Stresses to Calculate
You can select the stresses to be calculated in the list. When you select a check box, the corresponding stress is calculated.
A description of the selected stress is displayed to the right of the list.
Limit Stress
For each stress, you can select a limit stress type in the table. The stress ratio is calculated from the ratio of the existing stress to the limit stress.
If you want to increase or reduce the limit stress for a stress type, you can scale it accordingly in the "Factor" column. If you select the "/" option, the stress is divided by the factor multiplied by "*".
None
For the "None" type of limit stress, the calculation of the stress ratio is omitted.
Limit Normal Stress
The limit normal stress represents the allowable stress for the loading due to bending and an axial force. The limit normal stress is determined according to the following formula.
Limit Shear Stress
The limit shear stress indicates the allowable shear stress due to shear and torsion. The limit shear stress is determined according to the following formula.
Limit Equivalent Stress
The limit equivalent stress represents the allowable equivalent stress for the simultaneous effect of several stresses. The limit equivalent stress is determined according to the following formula.
User-Defined
You can use the "User-defined" limit stress type to adjust the limit stress manually. The limit stress can be specified in the "User-defined limit stress" column.
User-Defined Compression / Tension
The "User-defined compression/tension" limit stress type allows you to specify sign-dependent limit stresses for certain stress components.
Special Options
You can specify the settings for the stress calculation in the Special Options tab.
Modify von Mises Equivalent Stress
You can adjust the factors used to determine the equivalent stress. The factors affect the equivalent stress (von Mises, modified) σv, von Mises, mod.
