Hi everyone, i want to apply a fix force in 4 hours to one beam,i dont know how to work with transient structure.would you help me?

Since you mention 4 hours, this implies that inertial forces are insignficant so you can run this model in a Static Structural system. You only need to use Transient Structural if the accelerations get high enough where the inertia forces on the mass become significant.
You need to create a material with a viscoelastic or viscoplastic behavior to build a model that simulates the creep that occurs when a constant force is applied for a period of time.
Do you have experimental creep data from a material sample? That is most important.

hi peter, im working with a pressure vessel that works in specific working cycle:
1) 4 hours takes that its pressure become 0 to 103 Mpa
2) 4 hours holds 103 Mpa
3) 5 hours takes that its pressure beacome 103 Mpa to 0
i dont know how simulate this in static stractural or other parts
can u help me?
plz explain in simple mode im new with ansys.tnx
