## CAE and river dam

Dams are classified as timber dams, arch-gravity dams, embankment dams or masonry dams, with several subtypes. We have computing some simple dam during our termomechanics course. I’ll try to program a short program that visualizes the air and water tension that a dam has to cope with during my holidays. The forces are as following: we have air pressure that comes from up and water pressure that acts on a dam. The picture below describes a case that I have computed. We set coordinate system

as shown in the picture below.

## Deriving mathematical model:

E- Young.

## Using constitutive equations you get:

## Plane stress state:

## Example

Combining those computations to geometrical model of dam we can easily visualize stresses and distortion the pressure creates. As you can see, the computational model I have published here is not sophisticated. Nonetheless is true and provide a lot of fun and models quite good real dam (concerning it as a student exercise).
