Workbench Beam Stresses

Workbench Beam Stresses

Workbench Beam Stresses

(OP)
Hi all,

I'm currently working with ANSY WB version 12.0.

I have a steel pipe flange connected to an aluminium casting via three bolts.  To simplify the model I have modelled the bolts as beam elements in ANSYS Mechanical using the "connection - beam" functionality and joined my casting hole to the nut hole.  This works fine and I have managed to run my model.

I have added a beam probe which tells me the following:
Axial Force = 1074N
Torque = 20Nmm
Shear Force @ i = 408N
Shear Force @ j = 408N
Moment @ i = 1230Nmm
Moment @ j = 2569Nmm

The things I am struggling with at the moment are:

1) Identifying the sign conventions for the beam probe output and consequently drawing the FBD.

2) Calculating (by hand) a stress from these figures to allow me to compare it against fatigue material allowable stress ranges.

Any advice/guidance would be very much appreciated!

Dan
