Abstract(s) :

(Anglais) Several papers have already been presented in the literature to describe the methodology to assess strength of geomaterials with “partially-destructive” scratching tests. Experiments on several rock materials have shown that the intrinsic specific energy is well correlated to the strength of the rock. Here we give an overview of the principles behind the scratch test and present some particular field applications in which it has been performed to assess materials strength. The description of different applications points out the numerous possibilities to characterize materials strength even if samples are of poor quality, damaged, or too small to perform conventional tests
