DESCRIPTION:Underground man-made salt caverns are a proven technology for 
 energy storage\, and their usage is expected to increase in the coming yea
 rs\, following the current efforts towards energy transition. Upscaling sa
 lt caverns (e.g.\, systems of caverns) also raises concerns about safety a
 nd cavern integrity\, which requires a careful lifetime assessment of thei
 r mechanical stability. In this context\, this presentation examines the m
 echanical behavior and failure mechanisms of salt rocks\, as well as metho
 ds for identifying situations that could compromise cavern integrity. The 
 importance of a multiscale approach\, spanning from laboratory experiments
  to field-scale simulations\, is also discussed. Without diving into the m
 athematical details\, a physical intuition is provided on how to compose a
  constitutive model to capture the different deformation mechanisms in sal
 t rocks. Finally\, the impact of different constitutive model choices and 
 calibrations is analyzed in the light of numerical simulations.
