On Uniaxial Ratcheting of AlSi10Mg Prepared by SLM Technology

Popis výsledku v původním jazyce

This study examines benchmark experiments for a cyclic plasticity model. The aim was to investigate the influence of mean stress and stress amplitude on uniaxial ratcheting behavior. Data were collected from low cycle fatigue tests that were applied to the AlSi10Mg aluminum alloy manufactured by selective laser melting technology. Low cycle fatigue tests were performed in stress-controlled mode as a block loading in three different conditions. These conditions are in order, first, to keep the loading coefficient the same and change the stress amplitude and mean stress, second, keep the maximal stress the same and change the stress amplitude and mean stress, and third, keep the stress amplitude the same and change the mean stress. All fatigue tests were simulated using the Chaboche model to verify its ability to predict uniaxial ratcheting of the material. All simulations were done using Python code. It is difficult to describe the effect of the mean stress and the stress amplitude by the Chaboche model in the whole range of stress amplitude / mean stresses correctly.
