FRP Shear-Strengthened RC Beams: Re-examining the Shear-Crack Effectdoi:10.1061/(asce)cc.1943-5614.0001251ChenXiaoZhou
The problem of the penny-shaped crack imbedded into an infinite body of an incompressible power-law isotropic material subjected to remote shear stress is addressed in two ways. First, we conduct a detailed numerical analysis using the finite element program ABAQUS. This analysis provides accurate ...

Fatigue crack initiation and growth in tensile-shear spot weldments : McMahon, J.C., Smith, G.A. and Lawrence, F.V. ASTM Report No STP 1058 1990 47–77doi:10.1016/0142-1123(91)90436-3SDOSInternational Journal of Fatigue
Under the conditions of plane deformation, by using the Wiener鈥揌opf method, we perform the numerical analysis of a narrow small-scale process zone in the elastic body subjected to shear near the tip of an interface crack whose faces are in contact with friction. The process zone originates...
The influence of the shear in evaluating this distance is taken into account. A simple formula that gives the rotation capacity of shear crack hinges taking into account all the main parameters of the problem is the main contribution of the paper. This formula is compared with some analytical ...
rotation capacityreinforced concrete beamsIn this paper a theoretical model which provides the analytical expression of the ultimate plastic rotation available in shear crack hinges is presented. The rotation capacity is evaluated by integrating the mean curvature across the cracks over the distance from ...
Fatigue crack propagation behaviorIn this study, the fatigue crack propagation (FCP) of epoxy clay nanocomposites is investigated. Especially effect of size, aspect ratio and tactoid shear - stiffness of clay nanoplatelets are analyzed in detail. To achieve a systematical approach, two highly pure ...
