  3. Introduction • The current ATLAS beam pipe will be extracted and replaced by the IBL package • In order to study the IBL thermo-mechanical behavior and validate the beam pipe design, tests are performed on a mock-up of the IBL • Mock-up differs from the IBL in some aspect (material, geometries, loads and boundary conditions) • To establish a connection between the mock-up and the IBL package, thermo-mechanical simulations are essential • Furthermore, insteadof a locally evaluation of the interesting parameters also the complete field distribution can be obtained • FEM/CFD modelization of the mock-up during the two more difficult phases (bake-out and service operation) will be performed • An accurate numerical evaluation of the mock-up behavior allow the correct estimation of the thermo-mechanical load/deformation on the IBL TALENT Meeting – A. Sciuccati
