4th Indian International Conference on Artificial Intelligence (IICAI-09). IICAI-09 will be held during December 16-18 2009 in Tumkur (near Bangalore), India. IICAI is a series of high quality technical events in Artificial Intelligence (AI) and is also one of the major AI events in the world.
Dear all,
I am trying to simulate a three-laminated composite considering the cohesive effect between the interfaces.
How can I implement this in COMSOL? Are there any Samples to follow?
Thanks!

We perform uniaxial tensile tests on polyimide-supported copper films with a strong (111) fiber texture and with thicknesses varying from 50 nm to 1 μm. Films with thicknesses below 200 nm fail by intergranular fracture at elongations of only a few percent. Thicker films rupture by ductile transgranular fracture and local debonding from the substrate. The failure strain for transgranular fracture exhibits a maximum for film thicknesses around 500 nm.
I'm trying to determine the coorelation of a blade natural frequency and disk (nodal diameter) natural frequency on a Turbine wheel in ANSYS Modal analysis. Is it possible for a blade natual frequency to be excited even though a disk natural frequency is not being excited?? I'm having trouble determining if a blade frequency is related to any disk nodal diameter. Thanks for any incite on this subject.

I have had some time to write down an informal introduction to Moving Least Squares, from my coding perspective. It is supposed to be a condensation of experiences after some years of using it, although it does not contain any new theoretical aspect.

Dear everyone
If we considerer a 3D fracture stress and strain field as a combination of numerous 2D fields in thickness direction, the J integral at each 2D plane can be obtained according to Rice’s definition (Abaqus and Ansys also include this function). What I concerned is the ratio of J integral at the surface of SEB or CT specimen to that at the mid-plane of the specimen. What factors have influence on the ratio? How to find the quantitive relationship between the factors and the ratio in linear elastic model?

in case you need to explain the epsilon-delta definition of continuity to an engineering student.

The Department of Mechanical Engineering at the Universitat Rovira i Virgili (URV) (www.urv.cat) in Tarragona (Spain), is looking for several enthusiastic research students with a strong interest in fluid dynamics. Successful candidates will join a small but very active multidisciplinary team, working in fluid-structure interaction problems. The research will be mainly experimental and focused in the area of fluid structure interaction with application to several engineering problems.
