Generalization of the theory of critical distance to estimate lifetime of notched components in the medium-cycle fatigue regime [PDF]
MATEC Web of Conferences, 2019 This paper proposes a new and improved way to determine the dependency of the parameter that characterizes the process zone size ∫ with fatigue life Nf. Thus, unlike the classical approach, this approach has the advantage of allowing the construction of ...

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

The Theory of Critical Distances applied to multiscale toughening mechanisms [PDF]
Engineering Fracture Mechanics, 2019 Abstract The Theory of Critical Distances (TCD) is an approach used for predicting the effect of cracks and notches on fracture and fatigue behaviour. In recent years it has been successfully applied to a wide range of problems across all classes of materials.

Journal 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 ...

Theory of critical distances: A discussion on concepts and applications
Proceedings 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 ...

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

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

The effect of notch size on critical distance and fatigue life predictions
Materials & Design, 2020 Notch and size effects generally show great influence on the fatigue behavior of engineering structures, which plays a vital role during their structural integrity and reliability evaluations.

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