FRP-confined concrete model based on damage-plasticity and phase-field approaches

This paper is concerned with the finite element (FE) modeling of mechanical behavior for concrete columns wrapped with fiber reinforced polymer (FRP) materials under uniform compression load. The introduced model is based on modifying damage evolution in concrete and FRP considered as a brittle material. In this work, the Miehe phase-field approach is employed for capturing the damage in the FRP, whereas the damage in concrete is evaluated by...
