Applying load in abaqus
Applying load in abaqus
(OP)
Hello all,
I would like some input from more experienced analysts please. I am looking to apply a pressure to a surface which is not normal to the surface. Why? Because the surface is at 45deg angle to the x axis but the pressure loading is not. Is there anyway I can angle the pressure load at an angle relative the surface i.e. just like defining x and y directions of concentrated load. I have tried with surface traction with not much success and also I don't feel that surface traction is suitable for my problem.
Many Thanks

Add a coupling constraint between the point and the face.
Apply the force to the reference point.
I hope this helps.

Corus, do you mean resolve the pressure in the x and y directions. However, when I actually apply this in abaqus I will still be applying the pressure normal to the surface?
Would I need to solve this problem by applying a load using a user subroutine DLOAD?

Some points:
- pressure acts always normal to the surface
- if you have a traction acting at an angle it can be decomposed in a normal component and a shear component.
