An interesting question...
See the following site:
http://www.edge.org/q2008/q08_index.html
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.)
general, nonsymmetric iterative solver
I have a need to solve huge ( > 1 million ) linear system Ax=b. The matrix is sparse and nonsymmetric. Is there an optimal solver for this type of problems ? If yes, where can I find it ?
A message from Ken Chong (NSF): CDI panelists recruiting
The NSF is preparing to handle the review of preliminary proposals submitted in response to the Cyber-enabled Discovery and Innovation (CDI) solicitation.
Equilibrium equations for large deformations
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
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
Variational Theory: Variable-independence and Consistency
Variational theory of elasticity is surveyed in the context of mathematical logic in the present paper titled "Variational Theory: Variable-independence and Consistency" . The problem of variable-independence of variational principles raised by Professor Chien Wei-zang is discussed.
HELICOPTERS: CALCULATION AND DESIGN. VIBRATIONS AND DYNAMIC STABILITY
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.
