چکیده انگلیسی
The present paper is concerned with the modelling of both slow strain rate and constant load tests of austenitic steels in acid solutions containing sodium chloride at room temperature. In a phenomenological approach, based upon thermodynamics of continuum solids and elasto-viscoplastic damage, besides the classical variables (stress, total strain, and plastic strain), an additional scalar variable related to the damage induced by stress corrosion is introduced. An evolution law depending on the corrosive environment parameters is proposed for this damage variable. The model prediction is compared with curves obtained experimentally considering different strain rates in different solutions showing a good agreement.
