ansys magnetism

Submitted by naveenkulnt on

Could anybody help me out with my problem in ansys magnetic analysis??, Iam trying to do a 3-D magnetic analysis in ansys-10, I have a permenant magnet (a block) on the floor with the N-pole and S-pole along the x axis (x-y plane is the floor), then I have a piece of iron (cylindrical shape) fixed at a height ( in the z direction) to the roof (the magnet is on the floor and the piece of iron is on the roof with a small air gap in between them), please tell me how to simulate the magnetic problem and how to get the magnetic flux density on the iron piece

An interesting question...

See the following site:

And then, think: If you had to answer the same question, what would your answer be?

 

(BTW, I know I have quite a few comments to reply here, but somehow have not been able to find time to do so.... I will, soon enough... Anyway, in the meanwhile, wish you all a happy new year... And oh yes, I think it would  be great if mechanicians could share their answers to the above referred question too.)

Equilibrium equations for large deformations

Submitted by Konstantin Volokh on
education

Lagrangian or referential equilibrium equations for materials undergoing large deformations are of interest in the developing fields of mechanics of soft biomaterials and nanomechanics. The main feature of these equations is the necessity to deal with the First Piola-Kirchhoff, or nominal, stress tensor which is a two-point tensor referring simultaneously to the reference and current configurations.

An effective bead-spring model for polymer simulation

Submitted by Bin Liu on

An effective bead-spring model combining the advantages of large time steps of traditional bead-rod models and computational rigor of traditional bead-spring models is proposed to simulate the dynamic behaviors of flexible polymer chains with arbitrary longitudinal stiffness. The proposed model can be used to simulate many types of polymer chains or networks with different chain elasticity via a unified integration scheme with reasonably large time steps. The paper can be found at http://dx.doi.org/10.1016/j.jcp.2007.11.012

Looking for this book

 Hi Everybody, Im new to iMechanica. I must admit If I knew of it earlier it could have changed so many things in my life :). Im really glad to be here now. For a start I would like to ask if anyone has any links /sources to this book. I simply cant find it. Ive checked Amazon etc etc. Please help me find this book

"HELICOPTERS: CALCULATION AND DESIGN. VIBRATIONS AND DYNAMIC STABILITY "(Mil, M. L. ; Nekrasov, A. V. ; Braveman, A. S. ; Grodko, L. N. ; Leikand, M.) 1968.

Rgds.

Dominic.
