Direction of fastener shear force

[346gnu]

Hi,

Is there any way to tell the direction of the shear forces acting on a fastener?

We have magnitude but no components.

Thanks

Hi Steven,

I am referring to the advanced fastener

[346gnu]

Steven,

very helpfull, am about to give a try

Steven,

Did you manage to experiment?

My findings in CREO3.0 ...

MECH_BOLT_COMP_OUTPUT = TRUE

added WCS and local fastener csys shear forces to the .PAS file

As with beams, it is clear the x-axis is along the fastener and is the fastener axial shear force with a positive local csys vector from bottom to top of fastener. (This shear force = fastener axial force)

Despite being given y&z (transverse) shear components, a fastener placed in the model at an arbitrary direction relative to the WCS is still making me think which way y&z point and is making me think. I have to get my logic right..

Otherwise, everything seems to add up.

MECH_PRINT_INTERFACE_MEAS = YES

Gives the same additional .PAS file output as above.

Though we also get the following in the .RPT

FastenerX_intf_bend_momt

FastenerX_intf_norm_force

FastenerX_intf_shr_force

FastenerX_intf_tors_momt

So,

FastenerX_intf_shr_force + FastenerX_shear_force = total shear force
