The unprecedented energy intensities of modern hadron accelerators yield special
problems with the materials that are placed close to or into the high intensity beams. The
energy stored in a single beam of LHC particle accelerator is equivalent to about 80 kg of
TNT explosive, stored in a transverse beam area with a typical value of 0.2 mm×0.2 mm. The
materials placed close to the beam are used at, or even beyond, their damage limits. However,
it is very difficult to predict structural efficiency and robustness accurately: beam-induced
damage for high energy and high intensity occurs in a regime where practical experience does
not exist. The interaction between high energy particle beams and metals induces a sudden
non uniform temperature increase. This provokes a dynamic response of the structure
entailing thermal stress waves and thermally induced vibrations or even the failure of the
component. This study is performed in order to estimate the damage on a tungsten component
due to the impact with a proton beam generated by LHC. The solved problems represent some
accidental cases consequent to an abnormal release of the beam: the energy delivered on the
components is calculated using the FLUKA code and then used as input in the numerical
simulations, that are carried out via the FEM code LS-DYNA
