Finite Element Analysis of FRP Debonding Failure at the Tip of Flexural/Shear Crack in Concrete Beam [PDF]
, 2013 One of the most common failure modes of strengthened RC beams with externally bonded FRP is intermediate crack (IC) debonding of FRP initiated at the tip of flexural/shear cracks. This study presents a method, using extended finite element method (XFEM),

Evolution of injection-induced rock damage along fractures under thermo-hydro-mechanical coupling
Case Studies in Thermal EngineeringHot dry rock (HDR) reservoirs heat is extracted by injecting cold water into natural or hydraulic fractures. During injection, the rock around the fractures experiences repeated cooling and pressurization.

Simulation analysis of the evolution law of creep rupture crack extension in X-fractured rock body
Scientific ReportsCreep is the macroscopic manifestation of the process of generation, expansion, and penetration of microscopic cracks in a rock body. In this study, the GDEM continuous–discontinuous numerical simulation software was used to model a rock body containing ...

Notched graphite polymimide composites at room and notched graphite polymide composites at room and elevated temperatures [PDF]
The fracture behavior in graphite/polyimide (Gr/PI) Celion 6000/PMR-15 composites was characterized. Emphasis was placed on the correlation between the observed failure modes and the deformation characteristics of center-notched Gr/Pl laminates.

Freeze-Thaw Durability and Long-Term Performance Evaluation of Shotcrete in Cold Regions [PDF]
, 2017 This study’s aim was to evaluate the freeze-thaw durability of shotcrete in cold regions and predict its long-term performance. One benchmark mix design from the WSDOT was chosen to prepare samples for performance evaluation.

Simulation of microscopic fracture characteristics of fractured rock based on CZM-FDEM method
Scientific ReportsMicrostructural damage is an important cause of macrofracture in fissured rocks. To investigate the microscopic fracture mechanism of fissured rocks, a fissured rock model was established using the CZM-FDEM method.

Some Micromechanical Aspects of Damage and Fracture
Acta Polytechnica, 2000 The failure mode is described by means of elasto-plastic fracture mechanics and the main aspects of fatigue crack behaviour are itemized. The crux of the matter is the presentation of the pplicability limits of the three substantially different fatigue ...
