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

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.

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.

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 ...

Multiaxial fatigue life modelling using hybrid approach of critical plane and genetic algorithm

Fatigue & Fracture of Engineering Materials & Structures, 2015
AbstractThis paper presents a new hybrid approach for multiaxial fatigue life estimation, based on continuum damage mechanics theory and a genetic algorithm with critical plane model formulation. The hybrid model employs a genetic algorithm based setup for calibration with standard proportional and non‐proportional profiles to predict fatigue life for ...

A new multiaxial fatigue damage model based on the critical plane approach

International Journal of Fatigue, 1998
A path-independent parameter for multiaxial fatigue damage is proposed based on the critical plane approach. Both parameters of shear strain and normal strain excursion are considered in this parameter. An equivalent strain is made with both parameters by means of the von Mises criterion. Thus a new multiaxial fatigue damage model is given based on the

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 ...

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 ...

Multiaxial fatigue life prediction for various metallic materials based on the critical plane approach

International Journal of Fatigue, 2011
This paper summarizes an attempt to devise a simple method suitable for assessing fatigue lives of metallic materials subjected to both proportional and non-proportional loading conditions. This proposed approach consists of the maximum shear strain range, the normal strain range and the maximum normal stress on the maximum shear strain range plane. In

Damage Assessment in Fretting Fatigue Specimens with Micro-voids Using Critical Plane Approach

2019
In this work, the influence of micro-voids on damage severity under fretting fatigue conditions is analysed for a regular and a random distribution of micro-voids. The finite element method is employed to obtain the stress field during a loading cycle. The well-known Smith-Watson-Topper and McDiarmid multiaxial fatigue criteria are assessed by means of
