Potential for Strain energy

Submitted by ramdas chennamsetti on Mon, 10/01/2007 - 05:22

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

Alex Epstein's introductory entry for ES 240

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:

Final exam (70%)
Lab (10%)
Two take-home assignments (each worth 5%, total 10%)
Lecture-notes (10%)

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.
