Plasticity model for crash analysis
Hi,
can somebody please tell me what is the best plasticity model to simulate a high speed collision ,for example invoving a car and why?.

Contact analysis in Abaqus
Hi,
I created to solid models in two different files ecah solid model consit of nodes and elements and then imported these files into Abaqus. Now I have these two solid modles in two different files inside abaqus.
My questions now is: how can I import one of the models into the another for contact analysis?
Thanks
More replies to Yavari, fractals, strongly emotional disputes, and what really leads to Nobel prize
Dear Yavari
I have promised more replies on Mandelbrot, fractals, strongly emotive discussions in journals, and here is a coincise statement, which I take from a Nobel prize, prematurely passed away last year. I think it has a lot to teach (including the kind of attitude that leads to Nobel prize, i.e. close to no human weakness), you will recognize the real name of the "Caesar" in this book is somebody with a 58 pages CV on his web site, most likely.
For a better idea of fractals, read please the other attachment.

how to create mesh for curve lines in LUSAS
hi friends,
i need a help, on how to creat mesh to my model. my model composed of 2 curve lines and 3 straight lines.
when i assign surcafe to the model to create the mesh, the warning came out , which saying the it is something to do with non planar surface and when i check in index, it say something to do with support surface. As far as i concer the meshing must be bounded by 4 lines, not 5 lines as mine.
please any one help me on this..
thanks.

Jun. 30, submittion of one journal paper, which is the work of the Chapter 4 of my dissertation.
Another paper submittion in the meantime, the work of the Chapter 3 of my dissertation.
The maximum receptor-ligand bond spacing to ensure cell adhesion in ligand-coated substrates
Recent experiments by Arnold et al. (ChemPhysChem, vol. 5, 2004, p383 ) revealed that a distance of less than 58-73 nm between receptor-ligand bonds is necessary to ensure focal adhesion in cells adhering to ligand-coated substrate. An elegant solution to this problem is supplied by Lin, Inamdar, and Freund.

Is the limit of stress intensity factors "1" when the crack length is close to "0"?
I have read some papers about fracture mechanics of functionally graded materials. I find there are different results for the stress intensity factors when the crack length is close to "0" . In some papers the values of stress intensity factors are "1" when the crack length is close to "0" , but in other papers the values of stress intensity factors are not "1". I obtain the stress intensity factors is "1" when the length of crack is close to "0". I hope to get the explaination about the results.Thanks a lot.
Evalauation of shape functions for nodes on the boundary in weak form
I have a query regarding how to evaluate shape functions of nodes on the boundary (natural boundary conditions ) for weak from for mesh free method.
Mesh free method which I am using is Radial point interpolartion function for the interior nodes and mesh free weak from for the nodes at the boundary ....but facing trouble with the shape function to be used.
Thank you
