The damage scale concept and the critical plane approach

Fatigue & Fracture of Engineering Materials & Structures, 2017
AbstractCritical plane criteria seek the plane in which their damage parameter has its maximum value. On this plane, the fatigue damage of both normal and shear stresses is updated to the same damage scale by a constant, typically based on material normal/shear fatigue limits. This paper focuses on the damage scale concept under a stress‐based critical

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

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 Damage Calculation Using the Critical Plane Approach

Journal of Engineering Materials and Technology, 1995
The critical plane approach is applied to model material fatigue behavior under any constant amplitude proportional loading. The most critical plane and the largest damage parameter are determined in closed form for six damage criteria that have been proposed in the literature.

Lifetime of semi-ductile materials through the critical plane approach

International Journal of Fatigue, 2014
Abstract This paper presents the results of fatigue strength estimation depending on the variable orientation of the critical plane for proportional and non-proportional bending and torsion with regard to specimens made of aluminium alloy 2017A. The algorithm applied for the fatigue strength evaluation is based on the Carpinteri–Spagnoli proposal and

Damage Mechanics and Critical Plane Approach to Multiaxial Fatigue

Key Engineering Materials, 2013
The mechanical behaviour of structural components subjected to multiaxial fatigue loading is very important in modern design. Several approaches have been introduced in recent decades to analyse this problem. The so-called critical plane approach, based on the stresses acting on the plane where the crack nucleation is expected to occur, is widely used.

Failure Criterion for Structural Masonry based on Critical Plane Approach

Journal of Engineering Mechanics, 2002
The paper presents a macroscopic failure criterion for structural masonry. This criterion is derived within the framework of the critical plane approach. First, a general discussion is provided examining the performance of this framework in the context of classical linear as well as nonlinear criteria. Subsequently, a bilinear form of failure criterion

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

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.
