Analysis of damage-plasticity model of concrete under uniaxial compression loading

Concrete is a quasi-brittle material and shows different behavior in compression tension. It elastic at initial stage damage-plasticity beyond limit. Therefore, development of model concrete complex phenomenon. In this study, damage plasticity theory has been described under experiment on cylinder considering uni-axial loading interpreted with analytical data calculated using CEB-FIP code equation. The divided the stress-strain curve for into three sections according to concrete’s non-elastic behaviors. Those have considered calculate data. experiment, observed two phases. value stresses various points stress strain calculated. According data, up 8.3MPa point no occur within However, experimental only 2.28MPa occurred stress. Finally, percentage due obtained from analysis assessed compared. Above 32 percent found 22.5 MPa both cases.
