Dear Sir or Madam,
I am Mechanical Engineering student I have problems
with finding book with solved problems in Potential Flows,
Fluid Mechanics.
I would be grateful if you could recommend me
some book or other source wich contains many
solved problems of this matter.
Thank you very much.
Sincerely,
Oat
Hi,
I am trying to model a sheet of Poly Vinyl Butryl (PVB), which is a viscoelastic material in ANSYS. I have all the regular properties like elastic, shear and bulk modulus, poisson ratio, denstiy and damping factor. I also have a stress- strain curve of PVB. With all this data, is it possible for me to find the various constants in the viscoelastic models using ANSYS?
Thanks

Hi,
I want to medel an overhead line conductor in Abaqus. As you know, the suspended cable has a parapolic (or catenary) profile under its weight. There is a pre-tension (or pre-strain in elastic region) on the cable due to its weight.
I found in the help of Abaqus that I can use the "Bolt load" option to define the pre-tension, but it does not work for my model. Because my model doesn't have surface to choose for this type of load (it's a 2D wire part).
Would you please let me know how can I define this pre-tension (or pre-strain) in my model?
The concept of axis of of pure rotation ( or instantatious center of rotation) is a bit confusing. The text books in engineering mechanics( Irvin shames , Beer & Johnston etc) tells that the locus of points in a body, which is (are) having zero veloity. This fits well in case of a 2D motion. As a limiting case of this we are assuming the center of rotation is at inifinity for a rigid body moving in a straight line
Hi
iam looking for abaqus Umat/Vmat for functionally garded material, is there any one who can help me with sample or code?

I would like to know the amount of increase of steel shear modulus under pressure or compression. Any ideas, references, ... I'd appreciate your support in advance. Thanks.
Hi all, I am currently beginning research as a graduate student on meshfree methods, focusing on RKPM right now. I have not been able to find an exact definition of what exactly a reproducing kernel means. Could someone kindly define a reproducing kernel? According to W.K Liu et al, a good example of a reproducing kernel is a Fourier transform, but I can't grasp why is that so.
I have a question regarding simple torsion of a circular shaft with a uniform cross section. Given a hollow circular shaft with inner radius R1 and outer radius R2, length L, shear modulus G, fixed-free boundary conditions and applied torque T about the central axis, the equation for the rotation angle at the end of the beam is
phi = T*L/(J*G)
where J = pi/4*(R2^4-R1^4)
