hi people,
recently in our lab, i tried to pull a viscous damper of a motorbike it was difficult to pull but was easy to push.
it seemed to be similar to that of a syringe
is there any fundamental law behind that..
where does the resistance come when it is pulled

Dear Colleague:
You are cordially invited to attend a special Workshop on Probing the Limits of Strength, which will be held at Lawrence Berkeley National Laboratory on August 10-12, 2009. This workshop aims to bring together researchers with an interest in experimental and theoretical studies of the fundamental limits of strength in materials. The workshop will include a strong lineup of national and international speakers on advanced mechanical testing techniques and computational materials science of materials deformation at the elastic limit.

Hi Have for a period been searching for tutorials of how to build a composite (and doing an analysis, eigenvalue, Euler-buckling, first ply) model in Ansys.Have been able to find a couple of examples in the Ansys-portal examples search, have after reviewing the different options decided that shell91 will be a appropriate element type for me. (because of nonlinear capabilities)Referring to "152191 - Example of new Failure criteria (FC) method for shell91 vs. old method", shows the basics of how to build a composite specimen of 5 layers, and using new and old FC (Tsai-Wu).
I have designed a large boat trailer structure and FEA analyzed it statically.
Now, i want to know if it's possible in CATIA to compute the needed pulling force/power that the trailer will need to start moving. I assume a load of 200ton on the trailer frame and some frictional data must be entered to the wheels/ground contact surface. Anyone has ever done something similar before?
Dear All,
I am new to simulations of carbon nanotubes, especially in their mechanical properties. My supposed tools are ab initio codes or md codes. I am looking for some references. Can someone introduce some classical papers or leading experts in this field.
Thanks.
