Finite Element Modeling of Single Shear Pullout Specimens and Flexural Prisms

This paper presents the experimental and numerical investigation of the bond behavior between the carbon fiber reinforced polymer (CFRP) sheets and concrete surface. In this study, two Finite elements (FE) models were developed to study the bond behavior using single lap shear test and the flexural prism test. Three-point bending test was conducted for the flexural prism and load-deflection response was documented until specimen failure. FE models were developed using the multipurpose program ANSYS and the experimental results are used to validate the accuracy of the developed FE models. The results showed that there is good agreement between the FE predicted numerical models and the experimentally measured results until the elastic stage of the loading. The percentage difference between the experimental and numerical results is in the range of 4-9%. Hence, FE models are capable to capture the response of prisms under single lap shear test and flexural prism test with a high level of accuracy.
