Laser-driven particle acceleration, obtained by irradiation of a solid target using an ultra-intense (I>1018W/cm2) short-pulse (duration<1 ps) laser, is a growingfield of interest, inparticular for its manifold potential applications in different domains. Here, we provideexperimental evidence that laser-generated particles, in particular protons, can be used forstress testing materials and are particularly suited for identifying materials to be used inharsh conditions. We show that these laser-generated protons can produce, in a very shorttime scale, a strong mechanical and thermal damage, that, given the short irradiation time,does not allow for recovery of the material. We confirm this by analyzing changes in themechanical, optical, elect...
