PhD opportunity at Queen Mary, University on London, on numerical simulation of particle-laden interfaces

Submitted by lbotto on

A 3-year PhD scholarship is available to work on simulation methods to treat colloidal

particles that are flowing near, or are transported within fluid interfaces (L.

Botto et al., Soft Matter, 2012, 8, 9957-9971); the focus is on fluid

mechanical aspects coupled with physical-chemistry. For details: webspace.qmul.ac.uk/lbotto

NL springs query

Submitted by TheMig29 on

Hello guys,

I am working on a project wherein there is a rubber material which gets compressed. Now I have the force-displacement curve for this rubber material. I intend to represent the rubber with NL springs.

The F-d curve mentiones the specimen details as 5*100mm. This i beleive is the tested specimen. Now how can I consider this for the whole rubber model???

I have n number of springs connected in parallel. How can I consider this when I use a F-d curve?

 

Any help is appreciated.

Thanks.
