The formation of scratch groove is probably related to microscopic fracture, plastic deformation, and material removal. The scratch test surely gives us some important information on the damageability of glasses with v

Such effect was discussed in terms of degradation of the act

Accordingly, morphological investigations and micromechanical models are shown to be key factors for understanding the dynamic crack growth of filler-reinforced elastomers and high performance rubber blends. The non-linear dynamic behaviour is intensively studied

These composites were fabricated by hot-pressing. Hardness, fracture toughness and strength were measured from room temperature to
