CHABOCHE SINGLE MODEL CALIBRATION FOR BAUSCHINGER EFFECT

Resumo

In this work a study of Chaboche single model for Bauschinger effect characterization was performed
by using the Ramberg-Osgood relation to determine the Chaboche constants ( and

). A series of adjustment
were made to obtain specific values, and from these values a curve fitting was performed to determine Chaboche
constants. The analysis of Bauschinger effect was executed by finite element method and compared with
experimental data available in the literature. The results showed good agreement in comparison to experimental
analysis.
