I have a global model which has pressures and nodal temperatures applied.I drive the submodel using dofs 1-3 at the cut surfaces and the displacements show good agreement between global and submodel. My concern is temperature. Do i need to apply the global model temperature profile to the...

i want to calculate stresses and displacements for a component which is subjected to significant thermal gradient and vibration/dynamic inputs. to date the method consists of carrying out a frequency response analysis with material data input for the elevated temperatures. i am thinking that...

for a linear static analysis carried out with a unit load the stress and displacement at any other loading can be obtained simply by factoring by the ratio of the loads as the relationship is linear. my question is: can stress levels obtained from a frequency response analysis be factored in...

can you post your .inp file and i will take a look.

I have worked for 15 years as an abaqus consultant.If you let me know what you are looking for i can advise on the the best way forward which can be achieved on much more reasonable terms than a company like HKS/SIMULIA.

I always use true stress and true strain values when modelling material non-linearity in FEA.I have been told that when running NASTRAN SOL 106 i should be using engineering stress and strain values. Can anyone confirm if this is true.Thanks.

Any tips or links to modelling of an interference fit (in this case a bearing to brake drum) using NASTRAN thermal analysis.

FAO Greenlight Can you say which Japanese Motor manufacturer you worked for and can you confirm if the rotors machined using the new (increased damping) method actually went into production or was just a test/development idea which went no further.Thanks. W

Greenlight Thanks for that.It sounds like somehow the natural frequencies were lowered as a result of the application of current.I will try and find more detail.Thanks for your reply and if you get any more info it would be great if you could let me know. Cheers W

FAO Greenlight. I am very interested in the statement you made below.Can you expand on the method of applying current during machining and how (and how much) the resonant frequency changes.Any info links etc would be greatly appreciated. Thanks in advance. "Also, if a current was applied to...

I have a meshed model of a vehicle wheel hub and i am thinking of applying vehicle loads via an RBE3 spider from axel centre to the bearing contact surface on the hub.I have linear beam elements going from the RBE3 to the Tire Contact Patch position. Any thoughts on where to best restrain the...
