Abstract: The influence of grid refinement, load increment size, and concrete tensile strength on the nonlinear response of reinforced concrete finite element models is examined. Nonlinearity is limited to cracking of the concrete ...

Abstract: The effects of the shape of the descending branch of the tensile stress‐strain curve, fracture energy, grid refinement, and load‐step size on the response of finite element models of a notched concrete beam are studied. ...

Abstract: This work applies a two-state interaction integral to obtain stress intensity factors along cracks in three-dimensional functionally graded materials. The procedures are applicable to planar cracks with curved fronts under ...

Abstract: This paper describes the mode mixity of stress-intensity factors for surface cracks at weld toes located at the saddle point in circular hollow section X joints. The remote loading applies a ...
