Hi all
I want to model a part of my model with incompressible material properties. I had initially thought that a Poisson's ratio of 0.5 would return an error and so assumed Nu=0.4999. However when I later tried Nu=0.5 the model ran with no errors and the deformation patterns that were seen...
I want to assign a biphasic poroelastic material using CAE. I have isotropic permeability (k)and void ratio under permeability (material behaviour) and log bulk modulus, poisson's ratio and tensile limit under porous elastic (material behaviour).
However, every time I run the model it aborts...
Hey, I've been working on designing a vortex lattice method program in matlab but am a bit stuck on how to calculate the induced drag. Do i need to calculate how much the lift vector at each bound vortex is rotated by the induced flow along it (due to the change in the effective angle of...
Hi,
For a uni project we're trying to do a detailed design on a wing to reduce the induced drag, we have decided to use winglets to do this but have no idea where to start off for designing this. We were thinking of doing a simplified analysis of the wing and then testing the results with a more...
Hey,
I've been trying to use weissinger's seven point theory as a robust way to predict the lift distribution over a swept wing, only problem is I can't seem to calculate the influence coefficients.
The equation i've got is (in matrix notation):
{angle of attack} = [influence...
