Hi,

I am working on a coupled fluid structure problem , precisley on the elasto-acoustic mode, of a system consist on a cube which define the fluid domain coupled with an elastic plate.

The boundry conditions is:

- all the face of the cube is regid only the face coupled with the plate

- the plate is simply supported at the interface

Course Notes of Finite Element Analysis of Solids and Fluids by Prof. K .J. Bathe

I thought the mechanics community would be interested in the course notes of

Prof. K. J. Bathe on "Finite Element Analysis of Solids and Fluids". This

course was taught at MIT and now is available freely through MIT Open

Enjoy!

 

Weak form

During the study of FEM, I found the term "weak form" of differential equation, which is the integral form of a differential equation along with the boundary conditions for a boundary value problem. Now my question is that why the term "weak" has been used.
