The disturbed state concept (DSC) provides a general way for constitutive modeling of deforming materials. This paper presents the experimental and analytical results for the development of methodology for predicting the stress-strain response of concrete attacked by sulfate. Ultrasonic pulse velocity (UPV) is used to identify a function for disturbance (D). The elastoplastic model and simplified hydrostatic stress model are adopted for the definition of the relative intact state (RI) and fully adjusted state (FA), respectively. Thus, the stress–strain curve can be predicted using the DSC model based on nondestructive method. The comparison results show that the proposed constitutive model is satisfied with application in similar condition.
