Load applied over 90 days

Hi

 

How I can simulate a load applied to a wooden pallet over 90 days? Which could be the best considerations?

And with that results do a fatigue analysis.

 

Regards,

 

Abdiel

Is it a cyclical load applied over 90 days or is it a slooooooow load?  90 days period should qualify for quasi-static, no?

It is a load applied on a structure during 90 days, the same value all the time, every second.

So it is a staic load? Or is there a frequency content (i.e. an oscillation of some sort)?

Hi,

 

It is a Static load

So you answered your own question: it is a static load, so SOL101 is the way to go.  As far as fatigue, if nothing changes, you can't really fail in fatigue...

90 days sounds like a creep problem. Creep would require creep material properties and a nonlinear solution sequence - 106, 401 or 601,106.

Good point, Jim!
