Shaun, So if my bolt is made from high quality structural steel and I need to use the von mises and I can pretty much ignore the pronciple stress? I would need to load it until it reaches the yeild...

Thanks mark,I've seen that already in the previous pre/E-Creo releases was present a different color map for the element of the mesh, but, in my opinion, the difference was much small and you was not...

Mark, The other question I meant to ask is methods of managing the 'falling off the edge' when the clip snaps into place. Three things noted from previous work we've done, time steps need to be very...

Hi Gunter,I found the tutorial was difficult to follow. The work flow is not intuitive for a new user like myself. I am surprised that there is only one example available of half-sine shock approach as...

Hello Kevin,there are in fact only few, mostly rather old suggested techniques available on the PTC Technical Support web site. The Central Page article contains links to all the relevant ones:CS106224...

Hi Gunter, I'm afraid my attempt at aligning the gravity vector with the hook constraints and the COG didn't really change anything. I still get really high stresses at the padeyes. You can't easily...

Kevin To help you to begin to unpick the suggested technique, Consider only the 'dynamic time' part of the suggested technique for now. There are 4 key work flow steps: 1. Carry out a modal analysis...

Thin plate + contact
Hi all,I use Creo 2.I would analyze this assembly where we have two identical parts composed by a thin plate with 8 holes (for bolts that are simulated as fasteners) and a thin tube that is weld on the...
View ArticleRe: Thin plate + contact
Yes. If you check "Account for Stiffness" in the Fastener Definition window, you don't have to make two seperate runs to obtain the desired pre-load.
View ArticleRe: Thin plate + contact
Are you refering to the base where the tube connects to the plate?

"I just had a try and it took 40 minutes to solve the analysis with shell pair idealization (1536 elements) and 20 minutes without idealization (5342 elements) ." This is due to the constraint...

I played around with your model and it looks like neither will work; both thin-solid elements and prismatic elements cause issues with pairing the linked elements (which is due to the contact...

Re: Thin plate + contact
Try running the model with no shells, and no surface regions, as shown below. I just ran a quick check with no poblem using solid elements, but different load. I did add some material to represent a...
View ArticleRe: Thin plate + contact
For now the best compromise that I have found is by doing a volume region on the tube near the plate so as "divide the tube in two parts", applying thin elements on the upper part of tube.So it works,...

Thanks Steven, but my goal is to learn the right manner to use the new tools for meshing that Creo 2 gives compared to WF5.Is more for knowledge that for work.
