This is an open access article under the CC BY-NC-ND license (https://creativecommons.org/licenses/by-nc-nd/4.0 ) Peer-review under responsibility of the scientific committee of the Fatigue Design 2023 organizers Abstract The present work is concerned with the evaluation of the nonlinear behaviour of 316L steel used in several fields, industry, automotive, aeronautics, medicine .... subjected to cyclic movements. This investigation allowed us to analyze the different responses of steel in low cycle fatigue, and to perceive the phenomenon of Ratcheting leading, to the damage of the structure by an excess of plastic strain, under loading cycles. The prediction of the behaviour of the steel studied, reveals that the Ratcheting increases according to the average stress when the stress amplitude is constant, and decreases according to the attenuation of the stress amplitude when the average stress is constant. The simulation campaign allowed us to present an assessment, of the conditions favoring the acceleration of the Ratcheting, includes several scenarios of periodic loadings, with strain and stress imposed under uniaxial tension/compression. The predictions of this model are evaluated by subjected to cyclic loading within the software ZébuLon. 1. Introduction The study of the mechanical behavior of materials aims to know their response to a given stress. Several macroscopic phenomena appear during the alternating cyclic loading such as: accommodation, adaptation and the Ratcheting leading the structure to damage by the effect of the non-symmetrical alternating stress. This phenomenon has been a line of research which has gained momentum in the field of fatigue Kulkarni & al (2004), Lin& al (2011), Boussalih &al (2022). In several industrial sectors 316 L austenitic stainless steel is used for its performance and quality against corrosion. It is important to predict the response of the steel studied when it is cyclically stressed under the effect of strain and controlled stress Mazanova & al (2017),Boussalih& al (2019).The quality of the model to predict, the macroscopic elastoplastic behavior of 316 L is considered as a basic step for the description, of the hardening produced during cyclic loading Marco & al (2016),Belattar & al(2021). In the present work we have chosen the Chaboche model. This model is capable of translating the real behavior of materials; it is based on the use of a law combining an isotropic hardening and a nonlinear kinematic hardening .
