How to apply pressure of 0 to 0.409 MPa at constant for a time from t=0 to t=1.6ms?

[SteveFinnan]

I don't really get this.

I have a balloon and stent, and I need to apply an internal pressure on the inner surface of balloon. The balloon will expand, then the stent will expand as well.

However, when I review work done by other, I came up with this statement.

"As illustrated in Fig. 2, the balloon was subjected to an uniform internal pressure increasing from 0 to 0.409MPa at a constant rate for 1.635 ms"

You can see the attachment in Figure.

Thanks for your help

You can apply an amplitude to your pressure load.

@DanStro,

Do you mind explain a little bit more?

By amplitude, I assume this is the fatigue analysis.

you set an amplitude in the amplitudes part of CAE (load module), you would do an amplitude "tabular"
0,0
1.6,0.4 (if your units are ms and MPa)
Then you assign the amplitude to the pressure load, which you give value 1
