A correction in the algorithm of fatigue life calculation based on the critical plane approach

International Journal of Fatigue, 2016
Abstract The paper presents the algorithm for calculating the fatigue life taking into account the variability of coefficients occurring in the multiaxial fatigue criterion depending on the number of cycles to failure. The algorithm has been analysed under uniaxial cyclic loads and a combination of bending and torsion for four structural materials ...

Fatigue Crack Initiation in Threaded Fasteners Using the Critical Plane Approach

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">In this investigation, the stress and strain distributions at the first thread of a joint under cyclic uniaxial loads are examined by finite element analysis. The stress and strain histories of material elements along the thread surface are used in conjunction with multiaxial fatigue theories and the critical plane

Critical Plane Approaches for Multiaxial Fatigue Damage Assessment

1993
This paper reviews the evolution of the critical plane damage models and traces their origins from the early work such as that of Guest. Physical justification in the form of detailed observations of crack nucleation and early growth are provided for the models.

Drillpipe Fatigue Life Prediction Model Based On Critical Plane Approaches

Offshore Technology Conference, 1994
ABSTRACT The applicability of critical plane approaches to predict fatigue life expectancy of drillpipe is investigated. These approaches consist of physically-based damage parameters that are capable of handling complex axial, bending and torsional load histories.

Critical Plane Approach to Analysis of Failure Criteria for Anisotropic Geomaterials

2011
Numerous geomaterials such as rock and soil exhibit structural anisotropy related to material fabric elements such as crack pattern, bedding, layering, contact arrangements, among others. The fundamental problem is associated with the specification of effective properties of the representative material element, accounting for microstructure and defect ...

Critical plane approach with two families of microcracks for modelling of unilateral fatigue damage

Forschung im Ingenieurwesen, 2000
New multiaxial fatigue damage model based on the critical plane approach is proposed. Two different physical mechanisms of the fatigue damage development on each potential failure plane (critical plane) are considered. In general, each critical plane contains two families of a parallel microcracks.

Study of the Multiaxial Fatigue Life Influencing Factors Based on the Critical Plane Approach

Advanced Materials Research, 2011
The tension-torsion thin walled tube specimens were used as the researching object in this paper. The method of determination to the critical plane which has the maximum normal strain and maximum shear strain was expounded. The strain state on the critical plane under non-proportional loading was analyzed, and the unified prediction model was used to ...

A CRITICAL PLANE APPROACH TO MULTIAXIAL FATIGUE DAMAGE INCLUDING OUT‐OF‐PHASE LOADING

Fatigue & Fracture of Engineering Materials & Structures, 1988
Abstract— A modification to Brown and Miller's critical plane approach is proposed to predict multiaxial fatigue life under both in‐phase and out‐of‐phase loading conditions. The components of this modified parameter consist of the maximum shear strain amplitude and the maximum normal stress on the maximum shear strain amplitude plane.

Fatigue life prediction of copper single crystals using a critical plane approach

Engineering Fracture Mechanics, 2006
Abstract A critical plane multiaxial fatigue criterion was employed to predict the fatigue life of copper single crystals. The detailed stress–strain response was obtained through the constitutive modeling using a newly developed crystal plasticity theory. The constitutive model was capable of capturing the major deformation features of copper single

FATIGUE STRENGTH ANALYSIS OF THE WEB PLATE OF WHEELS USING CRITICAL PLANE APPROACH

Advanced Nondestructive Evaluation II, 2008
Railway wheels have been one of the most critical components in a railway vehicle. Fatigue design of railway wheel is one of the most important factors, because wheel failure can cause derailment with loss of life and property. Damage on the wheel can be divided into three types, such as the contact fatigue of the tread, the thermal fatigue of the rim ...
