This paper study the mechanical response of a granular solid subject to an impulse force. The proposed model simulate the behavior of an airport pavement structure. The analysis is performed on a representative volume element (RVE) under thermo-mechanical actions, as those produced by landing gear impact of an airbus A320 and variable high surface temperatures loads.

The model, implemented in COMSOL Multiphysics software, has been as developed to investigate the response under dynamic actions (by impact and sliding) with addition of thermal actions. We analyzed the state of stress and strain filed comparing the three load conditions (normal loads, thermal surface and normal loads, thermal and normal surface loads after 6 hours). The results of the simulation demonstrate sufficient reliability with the theoretical illustrated models.
