A new multiaxial fatigue damage model based on the critical plane approach
International Journal of Fatigue, 1998A 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

A Critical Plane Approach for LCF Evaluation of Gas Turbine Disks and Rotors
Volume 7A: Structures and Dynamics, 2019Abstract In order to safely increase gas turbine efficiency without issues of early damage and failures, component life evaluation must neither be too conservative nor too optimistic. The method used for designing the parts is supposed to be as accurate as possible, so that the subsequent application of the appropriate statistically ...

Random Vibration Fatigue: Frequency Domain Critical Plane Approaches
Volume 9: Mechanics of Solids, Structures and Fluids, 2013Frequency domain analysis offers a very efficient method for the fatigue durability assessment of structures subjected to vibration loading. It also allows engineers to gain valuable insight into system behavior and characteristics that are not easily recognized in the time domain. With some reasonable assumptions, most importantly linearity and steady

Failure Criterion for Structural Masonry based on Critical Plane Approach
Journal of Engineering Mechanics, 2002The 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

Hot-spot localisation according to the critical plane-based approach
International Journal of Fatigue, 2018Abstract The tubular welded joints in H-shaped structural components of agricultural sprayers are responsible for failure and the localisation of hot-spots is very important in multiaxial fatigue assessment of such components. Therefore, the purpose of the present paper is to develop a novel approach both to localize hot-spots in tubular welded ...

Fatigue Damage Calculation Using the Critical Plane Approach
Journal of Engineering Materials and Technology, 1995The 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.

A critical plane gradient approach for the prediction of notched HCF life
International Journal of Fatigue, 2005Abstract A new approach, which uses the Findley critical plane damage parameter along with the stress gradient at the notch, was developed for predicting notched HCF life. The proposed approach and methodology for HCF notch analysis accounts for: (i) the multiaxial stress state at the notch, (ii) the notch size effect, and (iii) the effect of fatigue

Lifetime of semi-ductile materials through the critical plane approach
International Journal of Fatigue, 2014Abstract 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

Multiaxial fatigue life estimation in welded joints using the critical plane approach
International Journal of Fatigue, 2009Abstract 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

An Energy Based Critical Plane Approach to Multiaxial Fatigue Analysis
1999A multiaxial fatigue damage criterion has been formulated based on observations that fatigue crack development is governed by stresses and strains acting on critical planes in materials. The damage parameter incorporates both Mode I and Mode II loading.
