Simulate: issue with measure on component interface for measuring shear

Hi @SB_10895015 ,

As already suggested through case 17616971. you might consider creating a new Creo Simulate coordinate system with axes along the desired direction/curve, and use an autogem control for hard curve.  A measure should then work on the hard curve. This could also be helpful in reviewing fringe plots with a capping surface applied that would allow you to perform dynamic query operations, and also manipulate legend values to query the results in depth.

Maybe the above could be a simple solution along with Maximum Shear quantity in Fringe plot (capping surface). You could also adjust results to show only one component, a surface of interest, etc. The main challenge is there is no conical coordinate system.

About Friction and contact, I do not expect you would know coefficient of friction of the bond since the epoxy in real like would encounter relative motion from bond/material failure rather than sliding/slippage.  Maybe the material data sheet might have this information, but it’s not something I would expect is typical.  If it is available, you could utilize the slippage measures as previously mentioned. Again, friction needs to be a known value, not something that can be measured.

Ideally, a solid model with known structural properties of the bonding agent applied would be a solid route.  While Creo Simulate generally handles linear materials (linear portion of stress strain curve of Steel for example), it does have elastoplastic and hyper-elastic non-linear material models as I shared with https://support.ptc.com/cs/cs_27/howto/mst12563/mst12563.htm

Lastly, perhaps a lesser known/used model type in Simulate might interest you, which is 2D axisymmetric.  These articles may be helpful as well: https://www.ptc.com/en/support/article/CS104684, https://www.ptc.com/en/support/article/CS52107, & https://www.ptc.com/en/support/article/CS202108

That idealized analysis type will not only run quicker, but will be even simpler if WCS is oriented as desired along bond interface, however, you can create a CSYS in Simulate along the bond interface to use for measures & other results.
