FRACTURE CRITERION OF THE THEORY OF CRITICAL DISTANCE FOR NOTCHES
Jixie qiangdu, 2018 Whether the brittle fracture criterion of theory of critical distance is suitable for graphite plates with different shape notches was studied by means of analysis of finite element: including tensile specimens with U notches,blunted V-notch specimens of

International Journal of Fatigue, 2020 Abstract The theory of critical distances is based on the definition of a material-dependent length L. Here, we investigate the statistical properties of L deduced from the crack threshold or a suitable notched specimen geometry. Monte Carlo simulations are done for best-fitting analytical functions to express mean, standard deviation and skewness of

The application of the Theory of Critical Distances to nonhomogeneous materials
Fatigue & Fracture of Engineering Materials & Structures, 2023 AbstractThe Theory of Critical Distances (TCD) has undoubtedly represented a breakthrough in the brittle failure assessment of engineering materials containing defects, crack, or notches. The basic idea on which the simplest formulation of the TCD is based is to evaluate an effective stress at a characteristic distance from the tip of the defect/crack ...

Critical length parameter of HDPE and its use in fatigue lifetime predictions
Fracture and Structural IntegrityThe contribution describes the fatigue lifetime predictions of polyethylene notched specimens based on the theory of critical distance. The approach uses the line method, which averages the axial stress over the critical distance.
