Add Event (Variable)
The Add Event (Variable) PropertyManager allows you to define a variable amplitude event for a fatigue study. You can define multiple fatigue events for one fatigue study. A variable amplitude fatigue event refers to one or more static studies, or to a particular solution step of a nonlinear or time history linear dynamic study.
The Simulation Curve library includes sample Load History curves from SAE.
The program uses linear theory. Scaling results is invalid if the static study includes nonlinear effects such as contact or large displacements.
For example if the amplitudes are measured in volts, the scale factor must relate Volts to the load in the study.
The load history can represent strain values.
If the model is subjected to multiple loads, define multiple studies with one load in each study. You can then define one event for each load case with the proper scale factor.
