A stress‐based method to predict lifetime under multiaxial fatigue loadings

Fatigue & Fracture of Engineering Materials & Structures, 2003
ABSTRACTThis paper extends to low/medium‐cycle fatigue a stress‐based method recently proposed by the same authors for high‐cycle multiaxial fatigue assessments. By considering the plane of maximum shear stress amplitude coincident with the microcrack initiation plane, the method requires the calculation both of the maximum shear stress amplitude and ...

Lifetime predictions for resin-based composites using cyclic and dynamic fatigue

Journal of Biomedical Materials Research, 2001
Because dental restorative materials undergo fatigue in use, testing is often performed in the laboratory to evaluate material responses to cyclic loading. The purpose of this study was to compare the lifetime predictions resulting from two methods of fatigue testing: dynamic and cyclic fatigue.

Lifetime Prediction of Thermo-Mechanical Fatigue for Exhaust Manifold

Advanced Materials Research, 2012
In this research, the non-linear thermo-mechanical simulation, experimental study and lifetime prediction of engine exhaust manifold were systematically analyzed. Fluid-structure coupled method was employed in the simulation. Heat transfer analysis simultaneous considered radiation, convection and conduction.

Fatigue Propagation Lifetime Prediction of Rotary Kiln Weld Shell

Applied Mechanics and Materials, 2010
Rotary kin shell is welded by cylindrical steel plates. Crack propagation of weld toes near supporting rollers until final fracture is the main failure form. Based on fracture mechanics, an overall intensity factor with regard to circumferential stress, concentrated stress, residual stress, and temperature stress is used to asses the crack growth ...

Novel Methodology for Fatigue Lifetime Prediction

1993
A unique fatigue lifetime equation offers the possibility of predicting residual fatigue lifetime of a material. Derivation of this lifetime equation is based on a correlation between the total and plastic strain amplitude during cyclic loading. A ratio determined as the reciprocal value of the elasticity modulus degradation is evaluated from the ...

Analysis of fatigue data for lifetime predictions for ceramic materials

Journal of Materials Science, 1978
Accuracy in data analysis is of utmost importance because lifetime predictions are extremely sensitive to experimental uncertainty in the crack growth parameters. The limitations of the conventional data reduction techniques used for analysing static and dynamic fatigue data are reviewed and new, statistical methods of data reduction that offer ...

Fatigue Crack Identification and Lifetime Prediction for Steel Bridge Deck Structures

Structural Health Monitoring 2015, 2015
Fatigue, as the governing degradation mechanism in steel bridge decks, can lead to non-inspectable cracks under the welded intersections of stiffeners to the deck plate. As a result, estimation of the remaining service life and optimization of the maintenance program of steel bridge decks become a great challenge.
