Compare Distorted and undistorted models:

S.NO

Undistorted Model

Distorted Model

1

An undistorted model is the one which is geometrically similar to its prototype. 

A distorted model is the one which is not geometrically similar to its prototype. 

2

The conditions of similitude are completely satisfied for such models

The conditions of similitude are  not completely satisfied for such models.

3

The design and construction and the interpretation of the undistorted model results are simpler.

It is difficult to extrapolate and interpolate the results obtained from the distorted models.

4

They are generally adopted for very small  projects (large scale).
