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 ...

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

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.

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

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

A correction in the algorithm of fatigue life calculation based on the critical plane approach
International Journal of Fatigue, 2016Abstract 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

Drillpipe Fatigue Life Prediction Model Based On Critical Plane Approaches
Offshore Technology Conference, 1994ABSTRACT 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.
