how to peform fatigue analysis in radioss ?

Hi,

In RADIOSS its not possible to perform a fatigue analysis. You can use OptiStruct for the same.

sir my loading is of short duration then how to perform fatigue analysis for the same ?

Hi,

How much is the short duration for the loading?. Since fatigue is failure under a repeated load the duration will be more for a fatigue analysis.

miliseconds .

Hi,

Fatigue failure will not happen in milliseconds time. In milliseconds, normally it will be a crash/impact analysis.

if my loading is in millisecond ?

Hi,

As mentioned before, a failure that can happen in milliseconds is a crash/impact case. 

Please elaborate on your analysis objective so that we can guide you.

a steel beam with cyclic load with loading time in the millisecond?

Hi,

We have tutorials in Help on fatigue analysis (OS-1340). Please go through the same and try solving with this time duration.

What are material properties required for the fatigue analysis in HyperWorks?

Hi,

I'm sharing a tutorial. Please review the same which shows the required material cards for fatigue analysis.
