Poisson's ratio data is not easy to obtain from simple tensile testing.
I've read multiple studies on the interwebs and there is not a lot of solid data on how Poisson's of steel changes with temperature.
I've seen studies that show 0.3 at 20C and 0.26 at 1000C.. but I've seen in the same...
Eng-tips members,
I have measured friction coefficient of 85 duro mixed rubber compound with no waxes or lubricants on smooth steel - the result is roughly 0.5. I would like extrapolate that data to 60 duro friction same basic rubber compound and same substrate.
Thanks,
Jeff C.
Eng-tips community, I'm sizing a throttle body and inlet hot and cold side vs the turbo inlet size, intake size, displacement, rpm. I'm an ME but I work on suspension not engines so please treat this like a noob question.
On a typical naturally aspirated engine larger throttle body seems to...
Hello the ultimate engineering forum, now that i have changed my focus from metallugry to fea - i need your help with rubber bushings in Ansys Workbench 13. I can get the solution to converge fine even with frictional contacts - no issues. However, i dont know where to start on the real...
I need to have both models shown in the 'project' directory in order to do a proper contact model via shrink fit. I can't even get to phase 1 because no matter what i do only one of my models shows up in the geometry section under the main project tree.
I can combine these using Designmodeler...
Hi, we now have an open Ansys license at work and I'm trying to get some work done before we can afford a class later this year.
Problem with an "invalid volume" error on solving.
using workbench trying to look at a sprung member in this case a suspension component. I used a parasolid input...
I am using an old Vishay 350a unit to measure residual strains in zinc castings that are overmolded on steel bar. I glue on the gage, then cut off the casting to see how much it shrinks after the tension is relieved. For some reason, the results are coming up low.
Is there a reason why this...
I am changing over from Zamak 5 to ZA8 for additional creep performance and to mitigate some issues with hot tears due to a large steel core.
One question i can't answer is where is the extra aluminum going? Zamak5 and ZA8 are essentially the same alloy except ZA8 has 8% Al vs. only 4% for...
The press fit force is a pretty cool equation that also incorporates poissons ratio. Here is a link to it.
My main question is why does increasing poissons ratio in the boss (outer ring of the pressfit, Eo above) reduce axial slip pressure, but when you increase poissons ratio of the shaft...
