Repeated instances of the same force on a design? (Siemens NX 12)

[tudwud]

Hi all,

I'm currently in the midst of designing a gaming mouse which can withstand '20 million clicks'.

I'm struggling to find on Siemens NX 12 how I can apply the same force X amount of times. I've ran standard tests using the 'Pre/post' simulation type, but I can't seem to run a test which allows me to apply the force a consecutive amount of times, and view the effects on my mouse button design. Any help would be greatly appreciated.

I understand this is a super basic question but I've lost access to my NX12 tutorial site login details, so I'm at a loose end as a newbie to FEA.

Thanks for your time.

This requires fatigue analysis. In such simulations you define the load, cycle type (probably zero-based in this case), run the simulation and read the number of cycles to failure (fatigue life) from the plot.

you want to run a time dependent loading (0 - max - 0 - max - 0 - ...)
