| 摘要： | A constitutive model based on the theory of plasticity is proposed and used to characterize the stress-deformation behavior of three epoxy concrete materials. It allows for factors such as stress hardening, volume changes, stress paths, temperature, cohesive and tensile strengths, and variation of yield behavior with mean pressure. It is applied to characterize behavior of three epoxy concrete materials. The constants for the model are determined from a series of available laboratory tests. The model is verified with respect to observed laboratory responses. Overall, the proposed model is found to be suitable to characterize the behavior of these three epoxy concrete materials. |
