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

Combined notch and size effect modeling of metallic materials for LCF using plasticity reformulated critical distance theory

open access: yesJournal of Materials Research and Technology, 2022
Fatigue assessment of notched parts plays imperative performance in structural integrity and reliability of major equipment. The theory of critical distance (TCD) involves determining the fatigue strength of notched parts from the linear elastic stress ...

Contextualism in Normative Political Theory and the Problem of Critical Distance [PDF]

open access: yesEthical Theory and Moral Practice, 2019
Political theory is contextualist when factual claims about context are part of the justification of normative political judgments. There are different kinds of contextualism depending on whether context is relevant for the formulation and justification of political principles (methodological contextualism), whether principles themselves are ...

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

A new proposal of effective stress and critical distance for fatigue at notches

open access: yesMATEC Web of Conferences, 2014
The Theory of Critical Distance (TCD) and its associated methods have proved useful for predicting fatigue and fracture failure under stress gradients. This work reports the first analytical deduction of the effective stress and its critical distance in ...

On the Transferability of Fatigue and Cyclic Deformation Data to 100 µm Thin Structures

open access: yesMetals, 2022
The fatigue properties and cyclic deformation behaviour of materials are usually determined using cylindrical specimens (e.g., Ø7.5 mm). Since the transferability to very small dimensions has not been comprehensively considered so far, this study ...

Study of Local Fatigue Methods (TCD, N-SIF, and ESED) on Notches and Defects Related to Numerical Efficiency

open access: yesApplied Sciences, 2023
The fatigue strength of structural components is strongly affected by notches and imperfections. Both can be treated similarly, as local notch fatigue strength methods can also be applied to interior defects.

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 ...
