PhD thesis for Alfa Laval Vicarb (le Fontanil, FR) & AB (Lund, Sweden), carried out in Mateis (INSA Lyon) & SIMaP (CNRS / Grenoble INP / UGA) laboratories.Title:Thermomechanical modeling & durability analysis of 316L welded plates heat exchangers.Abstract:This study proposes a simple methodology to estimate the mechanical response and lifetime of welded heat exchangers subjected to thermal loadings. The structure of the heat exchanger is modeled to estimate its mechanical response for thermal loads. Thermoelastic calculations are carried out with the finite elements method. From these simulations, the regions where the stress concentrates are identified. Then, a micromechanics approach is adopted to identify the material’s elastic plastic response with isotropic and kinematic hardening. Its durability under oligocyclic fatigue is investigated with an original 4 points alternate bending device. From these experiments, a Manson-Coffin criterion is identified. This criterion is used to estimate the heat exchangers lifetime in terms of maximum cycles for thermal loadings with different magnitude. To this end, the plastic deformation is estimated from the macroscopic calculation with an energy equivalence between the thermoelastic calculation and the non linear one. The predictions are found in agreement with experimental data carried out on test-heat exchangers, for both the thermoelastic response and the number at cycles at rupture.
