Introduction The increasing demand in lowering maintenance costs in engineering structures made of composite materials (e.g. aeronautics) contributes to the growing development of structural health monitoring systems.
For example, a method can give good results but samples must be small, or it does not work with all the materials, or it is difficult to use with high rates of production in industry, etc.
FE modeling of composites is more complex than of isotropic materials, particularly due to the presence of complex stiffness and variety of failure modes.

The selection of test materials allows us to compare a 6mm thick high-strength material with a 4mm thick ultra-high-strength material, since two of the three materials have approximately the same yield strength as sheet (Table 1.).
Some experiments were carried out on one of the test materials (CP960).
Test materials were formed by air v-bending.
All materials lose contact with the punch.
Edge damage was similar in all test materials.
