Thank you all for the input. I too am a bit curious/frustraed about the issue because some jurisdictions ARE trying to require a "defined" fall zone. I have not been able to get them to answer my qiestion as to what they want but, at the same time they want me to state/certify that the pole...
I work primarily in the communications structures arena designing monopole structures. Requests from jurisdictions have begun to come in for fall zones and fall zone requirements. A focal point "buzz" phrase has emerged requesting or requiring "self-collapsing" monopoles.
Poles generally fail...
Just a quick note on Hyper and FEmap. I haven't looked a the latest version of either......I am an ANSYS grinder..........But each, as most have at one time or another had difficulty with the tet meshing in thin field volumes. They had a tendancy (again, last time I tried them) to create very...

Sorry for the delay. I got sidetracked over the last week and lost track of this thread. Hopefully you found your answer. If not, what I think you are looking for is a displaced mode shape plot. Your desired frequency is at 15200 cpm whicj corresponds to 253.3 Hz. Your Modal solution...

Sorry to disappoint you but the model files I have produced over the years are the property of and in the possession of the engine companies I have worked with.
If I get some time later today, I wll try and get you a small model set up for this type of anlaysis. IT is quite simple...

it's been a long time since I used the FEMAP translater but I do seem to recall this characteristic. If I remember right I had to colect all the similar reals and do an emodify to reduce the number of reals.......not a great answer but a solution non the less.
Good luck
All Right, All Right..........Let's put the rubber on the road.......
I've got a BS and MS in CE (Structures Specialized in both)and have ~15 years doing FEA in the Aero and civil fields. The first couple of years I did a bang up job building models and pretty pictures but couldn't get answers...

Sorry, forgot to answer part 2 of your question. I would fix the 3 translations at the bolt locations for a simple solution. Reality of the situation is that it isn't cost effective to model the fastening with anything more than a point load. It is often reasonable to couple all of the...

What you need to do is run a modal analysis of the plate with boundary conditions (temperature, ux,uy,uz). If I read your inquiry correct you don't need to apply a dynamic loading. You onbly need to run a dynamic loading to obtain dynamic stress levels. Plot your mode values on a...
Adam,
You have a simple transient thermal/stress coupled problem. Unfortunately, I can't walk you completely throught it from this vantage point however.....perhaps I can point you in the correct direction. You have a transient thermal event occuring. By definition, the temperature of your...
Mr. Jones
Heer in the states there are several ANSYS Support Distributors in place. I would recommend contacting the main office in Pennsylvania, USA. Also, the current price for a single user mechanical license is available in the US$20,000 to $28,000 range...depending on your needs for...
