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 estimation in welded joints using the critical plane approach

International Journal of Fatigue, 2009
Abstract Many engineering structures experience multiaxial fatigue states of stress–strain in the vicinity of welded joints. Fatigue assessment of welded joints under proportional (in-phase) cyclic loading can be performed by using conventional hypotheses (e.g., see the von Mises criterion or the Tresca criterion) on the basis of local approaches. On

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 ...

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 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.

New strain energy-based critical plane approach for multiaxial fatigue life prediction

The Journal of Strain Analysis for Engineering Design, 2019
Based on critical plane approach, this article develops a new damage parameter through combing the equivalent strain energy aspect for multiaxial fatigue analysis, which includes no additional fitted parameters and overcomes the deficiency of using only equivalent stress/strain criterion separately under multiaxial loadings. Then, experimental data of

Critical plane approach for the assessment of the fatigue behaviour of welded aluminium under multiaxial loading

Fatigue & Fracture of Engineering Materials & Structures, 2003
ABSTRACT Multiaxial stress states occur in many welded constructions like chemical plants, railway carriages and frames of trucks. Those stresses can have constant and changing principal stress directions, depending on the loading mode. Latest research results on welded steel joints show a loss of fatigue life for changing principal stress directions ...

Low-cycle fatigue assessment of mooring chains based on the critical plane approach [PDF]

, 2020
The integrity of mooring chains is important to the safety of a range of offshore platforms for the exploitation of natural resources, including oil, gas, wind, and wave energy sources. However, mooring line failures have been occurring earlier than they are designed for with a high number of these failures occurring due to fatigue.
