Hi all, I'm hoping there's someone here who can give me a little help. So I've run a large number of fatigue tests, both stress and strain controlled, and using the data from these I've calibrated material constants for the chaboche model in Abaqus and run the simulations getting fairly similar...

Hey, thanks for the help. I got a CFM value from the compressor data sheet of 5.8. I converted it to 0.002454 m3/sec and then that to 195 m/s by dividing by the csa. Are my maths right here? That would give a mach of 0.57 and so it must be compressible right? Thanks again.

Hey all, So in relation to another question I've posted, I need to apply a distributed pressure in Abaqus on a compressor nozzle. Up to now I was just applying a uniform pressure throughout but I'm wondering how I would apply a pressure distribution? Also would it be simpler to just apply the...

No I don't although I could probably take a value from a compressor data sheet and assume the same?

Thanks for the reply. How would I go about doing this as I only know the pressure is 15 bar?

Hey all, So I have a small convergent nozzle that I'm modelling in Abaqus and I'm wondering how I could work out the pressure distribution so I can apply the correct load. The problem is I only know the pressure being fed to it by air compressor. Is there a way to use Bernoulli s or some other...

Homework Statement Homework Equations See above photo. The Attempt at a Solution [/B] Hey guys, I'm stuck on this equation never done anything like it but apparently its due to come up on exam next week. Any ideas on where to go with it so far...i stopped as i was about to remove the...

Hey Everyone, so I have just started Aerodynamics and having completed a number of exercises I'm being asked to design an airfoil. I'm a bit outta my dept as I've transferred into this course from a diff field. 1. Homework Statement To design an airfoil, using the knowledge you've acquired in...
