Static and Dynamic Techniques for Nondestructive Elastic Material Properties Characterisation

Different non-destructive techniques are developed and adopted for effective and reliable characterization of advanced composite material properties. Static approach using a three-point-bending test and two dynamic methods: impulse excitation and inverse technique based on vibration tests are applied to study the elastic properties of orthotropic laminated composites and aluminium alloys with different carbon nanotubes volume content. An experimental evaluation of the mechanical material properties of modern composites gave the possibility to validate the developed nondestructive techniques, demonstrate their advantages and universality.
