Ewann Gautier from IRDL presents an advanced modeling of cyclic plasticity to improve the durability of structures in Benin

Ewann Gautier from the National Polytechnic Institute of Brittany has developed an advanced modeling method for cyclic plasticity, allowing a 20% reduction in the radiocrystallographic parameter during tensile tests on C45 and HLE steels. This research, supported by experimental results, aims to anticipate fatigue failures and enhance the safety of structures in Benin.

Research on multiaxial cyclic plasticity is crucial for materials engineering, especially in the face of premature structural failures. Components subjected to heterogeneous stresses, due to various factors, require precise modeling. Ewann Gautier's thesis introduces an adjustable localization operator, allowing for the analysis of these complex behaviors and improving the understanding of plasticity mechanisms.

Experimental results, obtained through X-ray diffraction, show a 20% decrease in the radiocrystallographic parameter, with an uncertainty of 3% to 13%. These advancements allow for better anticipation of fatigue failures, a major issue for the durability of structures. The method developed by Gautier offers promising prospects for the construction sector.

The implications of this research are significant for decision-makers and the field. By improving the durability of structures, advanced modeling methods can reduce the risks of collapse and enhance building safety. Investors should support the adoption of these new methods to capitalize on the savings achieved through reduced failures.
