Position available / thin film and surface mechanics
“Surface du Verre et Interfaces”, a joint CNRS/Saint-Gobain research laboratory in Paris, is hiring a research scientist to strengthen its activities on thin films mechanics. For more information:

The second half of the last century saw exciting developments in formulating mathematically rigorous yet physically well founded theories for irreversible thermodynamics in a continuum mechanics framework. The development took place within communities with widely different scientific backgrounds and motivations. In general, two divergent schools existed (and possibly exit): one of them having its roots in the works of I. Prigogine and S. R. de Groot, and the other initiated by C. Truesdell, B. D. Coleman and W. Noll.
Hi all,
When a conservative force does work, it is independent of the path, we define the potential and work done is given by - (change in potential).
We define potentials for gravitational force, electrical force etc...
Assuming the body is linear elastic, internal forces, cause stresses in a body, are also conservative forces, whose work (strain energy) is independent of the path. Can we define potential for such internal forces? If so, we can calculate strain energy = -(change in potential).
You may kindly explain this.
Hi,
I am currently working as a Design Engineer-CAE in Bangalore,India.Presently interested in doing a MS/Mtech in the field of Mechanical Design and analysis through a distance learning program/part time course.It would be great if someone suggests an university(in India/abroad) where these kind of courses are offered.
Regards,
Ankita
Prior courses in solid mechanics: "Mechanics of Solids and Structures" was FBD's and strength of materials, and "Special Topics in Mechanical Engineering" focused more on building and aerospace structures. But no prior solid mechanics course, per se.
Undergraduate major: Engineering, concentration in Materials Science
The assessment includes:
Assessment results will be not be posted online. Online activities are for discussions only, no grading based on that. The first course-assignment will be given in 19/10, Friday.
1) A+B= (0,2,0)
2)A-B= (2,0,0)
3)2A+3B=(-1,5,0)
4)A.B=0
5)A*B=(1.0 - 0.1) - (1.0 - 0.-1) + (1.1 - 1.-1) = (0,0,2)
HOW MANY POINTS I GET THEN?
