Calculate and display maximum alternating stress

This example shows how to create a result probe to calculate maximum alternating stress, using this equation:

(Maximum principal stress-Minimum principal stress)/2

The model is a multiphysics model with eight load sets that apply loads from 1000 to 8000 seconds.

To calculate and display maximum alternating stress:

1. Choose Result Variables and create a result variable to define the temperature load at nodes.Name = MaxPrinResult Type = StressLocation = Element-NodalComponent = Tensor, Max PrincipalCombination = Element ValueCriterion = AverageOKYou set the Combination options so that the nodal values are averaged for each element.

2. Create another result variable for the minimum principal stress, named MinPrin.

3. Choose Result Probe and create a result probe to generate the maximum alternating stress.Name = MaxAlternatingStressFormula = (maxprin-minprin)/2Loadcase Selection = AllIteration Type = AllSelection Type = Entire Model

4. Generate output as a post view.Output Options = Post ViewCreate Output OK
