In this paper the capability of Gurson-Tvergaard-Needleman (GTN) model in the prediction of ductile damage in 7075-T651 aluminum alloy is investigated. For this purpose, three types of specimens were tested: Standard tensile bars, Round notched bar (RNB) specimens and compact tension (C(T)) specimens. Standard tensile bar tests were used to obtain the mechanical properties of the material and t...

Reinforced concrete (RC) beams may require flexural strengthening due to the corrosion of reinforcing bars or changes in design load. The near surface mounted (NSM) and externally bonded (EB) techniques, using either glass carbon fibre-reinforced polymer (GFRP CFRP) composites, are used for deficient RC beams. However, strengthened with both techniques susceptible debonding failure FRP composit...

Recently, researchers’ efforts have been directed toward using fiber-reinforced concrete (FRC) in lieu of conventional to improve the compressive strain, tensile strength capacity, cracking patterns, and ductility polymer (FRP) reinforced members. In this study, a numerical one-factor-at-a-time parametric study including 144 finite element (FE) models was performed ABAQUS 6.14 software deeply e...
