FRACTURE CRITERION OF THE THEORY OF CRITICAL DISTANCE FOR NOTCHES

open access: yesJixie 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

A review on the application of the theory of critical distance towards concrete [PDF]

open access: yesMATEC Web of Conferences, 2018
Theory of Critical Distance (TCD) is one of Fracture Mechanics numerical model that has gone through tremendous laboratory works and validation. Hence, it has been proven to be precise in broad perspectives in the field. Recently, TCD research related to

Statistical properties of threshold and notch derived estimations of the critical distance according to the line method of the theory of critical distances

open access: yesInternational 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

open access: yesFatigue & 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 ...

Duality of singularities of multiscale damage localization and crack advance: length variety in Theory of Critical Distances

open access: yesFracture and Structural Integrity, 2019
The existence of two singularities related to the stress field at the crack tip and blow-up kinetics of damage localization is considered as the physical basis for the interpretation of the Theory of Critical Distances.

Theory of critical distances: A discussion on concepts and applications

open access: yesProceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2021
Theory of Critical Distances (TCD) collects several methods adopted in failure prediction of components provided with stress concentration features. The idea of evaluating stress effect in a zone rather than in a single point was proposed decades ago but, only thanks to relatively recent works, TCD concepts showed to be a successful extension of Linear
