Description

There are many methods to measure the properties of composite materials. For instance, the elastic constants of orthotropic composite materials can be identified from the measurement of waves velocities by cutting the samples in various directions to access to all constants [1]. These destructive measurements are not available when the purpose is to follow the evolution of materials after or during the exposure of a damage (stress, corrosion, temperature ...). Composite materials are often made of the plies superposition in the shape of thin plates [2]. So, the well-known immersion method [ 3,4,5, 6 ... ] is very well adapted to the non-destructive evaluation of plate shaped, orthotropic materials.
