A critical plane gradient approach for the prediction of notched HCF life

International Journal of Fatigue, 2005
Abstract 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

ASME Sec VIII Div 3 Fatigue Life Predictions Using Critical Plane Approach

Volume 5: High-Pressure Technology; Rudy Scavuzzo Student Paper Competition and 23rd Annual Student Paper Competition; ASME NDE Division, 2015
ASME VIII Div 3 fatigue evaluation is based on the theory that cracks tend to nucleate along the slip lines oriented in the maximum shear stress planes. This code provides methods to calculate the fatigue stresses when the principal stress direction does not change (proportional loading) and axes change (nonproportional loading).

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

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.

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 ...

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 ...

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

CRITICAL PLANE APPROACHES IN HIGH‐CYCLE FATIGUE: ON THE DEFINITION OF THE AMPLITUDE AND MEAN VALUE OF THE SHEAR STRESS ACTING ON THE CRITICAL PLANE

Fatigue & Fracture of Engineering Materials & Structures, 1998
Critical plane approaches are useful methods when designing against long‐term fatigue of machine components made from metals. Somewhat surprisingly, the very basic problem of the evaluation of the amplitude and mean value of the shear stress acting on the critical plane is still not resolved satisfactorily for non‐proportional cyclic loading conditions.
