Research ArticleOpen accessEvery word in the titleAdvanced XFEM Simulation of Pull-out and Debonding of Steel Bars and FRP-Reinforcements in Concrete BeamsNicola Orlando, Elena BenvenutiAn innovative three-dimensional model is applied to the pull-out of steel bars and the debonding of FRP plates from concrete specimens. The shearing and opening modes at the interface of debonding is fully captured. The model is based on an innovative variant of the regularized eXtended Finite Element Method (XFEM) developed by the authors. In this method, the displacement discontinuity … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 6 Oct 2016 · 8,289 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleRobustness of XFEM Method for the Simulation of Cracks Propagation in Fracture Mechanics ProblemsAniello Riccio, Umberto Caruso, Antonio Raimondo, Andrea SellittoIn the present paper a numerical sensitivity analysis is presented with the aim to assess the effectiveness of the X-FEM method for fracture mechanics applications. Different test cases have been adopted for the numerical analyses to point out the X-FEM method behavior in 2-D and 3-D elastic and elasto-plastic conditions. Comparisons with a standard ductile damage model have been carried … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 15 Aug 2016 · 8,287 accessesView PDF Cite
