Pessard (PDF) Modified Kitagawa-Takahashi diagram accounting for The KitagawaTakahashi (KT) diagram [1] is a widespread tool for fracture mechanics based design of components and fracture control concepts such as the safe-life or fail-safe concepts.

A Flexible HCF Modeling Framework Leading to a

This article describes a flexible modeling framework which leads to the construction of a probabilistic, multiaxial Kitagawa-Takahashi diagram. This framework has been developed following experimental observations that clearly indicate that two independent fatigue damage mechanisms can be activated, at the same time, in metallic materials. A PROCEDURE TO OBTAIN THE PROBABILISTIC The proposed approach is applied to a notched plate made of P355NL1 steel, the results of predictions are analyzed and the deviations discussed.

A mechanistic approach to the Kitagawa-Takahashi diagram

It is proposed that this diagram represents two distinct fatigue damage mechanisms:one associated with crack initiation (or microstructurally small cracks) and the other with crack propagation (or long cracks). It is further postulated that these damage mechanisms are more appropriately modelled using di erent fatigue criteria. A new approach to model the fatigue anisotropy due to non A mechanistic approach to the Kitagawa-Takahashi diagram using a multiaxial probabilistic framework PESSARD, Etienne ; BELLETT, Daniel ; MOREL, Franck ; KOUTIRI, Imade ( ELSEVIER , 2013 ) The aim of this paper is to propose a flexible multiaxial modelling framework that is capable of combining two fatigue damage mechanisms so as to Analysis of Subcritical Crack Growth Using Kitagawa Jul 31, 2019 · In this paper, we analyze the fundamentals of crack initiation and growth contributing to fracture in materials using the modified KitagawaTakahashi diagram. The analysis, in principle, is applicable for all subcritical crack growth processes in materials.

Crack diameters were defined as 0.02, 0.05, 0.1, and 0.15 mm. Influence of semi-circular surface cracks was investigated by means of KitagawaTakahashi diagram and El Haddad equation. Assessments were done for survival probability of 99% on detailed FE model with normal metric thread profile and preload force at 70% of force at bolt yield point. KitagawaTakahashi diagrams define the limiting As cyclic fatigue is considered to be a major cause of clinical tooth fractures, achieving a comprehensive understanding of the fatigue behavior of dentin is of importance. In this note, the fatigue behavior of human dentin is examined in the context of the KitagawaTakahashi diagram to define the limiting conditions for fatigue failure.

Modified Kitagawa Diagram and Transition from Crack

Kitagawa-Takahashi diagram combines the endurance limit of a smooth specimen and the crack propagation threshold in a fracture mechanics specimen into single diagram thus providing the connection between the stress or strain-life and damage tolerance approaches. The diagram is modified by considering that (a) fatigue requires two independent load-parameters for unambiguous On the application of the KitagawaTakahashi diagram to Sep 01, 2002 · This approach was based on a KitagawaTakahashi diagram where the limiting conditions for failure in this case were defined in terms of the stress-concentration corrected smooth-bar fatigue limit (at microstructurally small cracks sizes) and the worst-case threshold (at larger, homogeneous continuum-sized crack sizes).

Technical Note

an approach is afforded by the Kitagawa-Takahashi diagram.25 Accordingly, in this note a Kitagawa-Takahashi dia-gram for the fatigue failure of human dentin is pre-sented. It is believed that a similar diagram could also be readily constructed for human cortical bone if appropriate data were available, and that this method- The Anisotropic Fatigue Behavior of Forged Steel A mechanistic approach to the KitagawaTakahashi diagram using a multiaxial probabilistic framework. which leads to the construction of a multiaxial Kitagawa-Takahashi diagram, is used.A mechanistic approach to the Kitagawa-Takahashi diagram The aim of this paper is to propose a flexible multiaxial modelling framework that is capable of combining two fatigue damage mechanisms so as to continuously describe the Kitagawa-Takahashi diagram.
