Creating a superposition event

Using the Superposition Event command, you can create a superposition load event that lets you define superposition of load histories with many finite element results.

Creating a superposition event includes:

• Importing the stress or strain results from a finite element result file, or selecting a solved solution in the current Simulation file to retrieve the results.

• Importing the data source files that contains the load histories. A load history may be in the form of force, displacement, acceleration, velocity, and so forth.

• Assigning the stress or strain subcases in the finite element results to the applicable loads.

• Optionally defining the static loads, a pre-stress case, and a temperature source load.

You define a superposition load event when you have different loads acting on a model. To retrieve the local stress or strain time history, a linear superposition of the stress or strain subcases caused by each load is required. For a static superposition, each subcase describes the stress or strain distribution on the model when one of the loads is excited and all the others are zero. When multiplying the subcases with the loading history, a stress or strain history is induced on the model. If several loads are acting on the model, all their contributions are linearly superimposed to retrieve the total stress or strain history on the model.
