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

Journal of Biomedical Materials Research Part B, 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.

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 ...

The predictions and applications of fatigue lifetime in alumina and zirconia ceramics

International Journal of Fatigue, 2004
Abstract The lifetime prediction of ceramics has been discussed on the basis of the relation between the stress intensity factor KI and the crack velocity V. In this paper, the effects of both cyclic loading and water environment on the KI–V characteristics were studied by the crack growth tests using the double torsion method under static and cyclic

Lifetime prediction of fatigue sensitive structural elements

Structural Safety, 1993
Abstract The propagation of uncertainty from the mechanical and geometrical properties of a structural element to fracture mechanics parameters, as the stress intensity factor and the J integral, is studied using a stochastic finite element method.

Lifetime Prediction for Fatigue Damage in Bonded Joints

Key Engineering Materials, 2003
A procedure is outlined and programmed in software in order to predict the fatigue threshold in composite adhesively bonded joints. Two different joint configurations are considered in this study, namely, Double Lap (DL) and Lap Strap (LS). The substrates are made of either uni-directional (UD) or multi-directional (MD) composite laminates and bonded ...

Isothermal Fatigue Lifetime Prediction of Solder Materials

Mechanics and Materials for Electronic Packaging: Volume 1 — Design and Process Issues in Electronic Packaging, 1994
Abstract Accurate prediction of fatigue lifetime is an essential ingredient in the assessment of structural reliability of existing solder materials and in the design of new ones. A micromechanical method for the prediction of fatigue life of solder was developed by Zubelewicz et al. (1989,1990).

Fatigue Lifetime Prediction for Uncertain Systems

1994
Fatigue life prediction deals with factors which can be modeled as random variables, random processes or stochastic fields. Given a probabilistic definition of these factors, the life distribution results from a reliability analysis. The advanced mean value first order (AMVFO) method was suggested to minimize the number of functions to be evaluated in ...

Alternative Fatigue Lifetime Prediction Formulations for Variable-Amplitude Loading

Journal of Solar Energy Engineering, 2002
Accurate prediction of lifetime is an increasingly important issue for wind turbine rotor blade materials. Coupon tests with the variable-amplitude standard loading sequences for wind turbines known as WISPER and WISPERX have indicated that the coupon lifetime can be overestimated by one or two orders of magnitude using conventional lifetime prediction

Relating fracture mechanics and fatigue lifetime prediction

Materials Science and Engineering: A, 2016
This article presents how to link together the results of fatigue crack growth tests, analytic fracture mechanics and experimental methods of fatigue lifetime predictions. The study at the beginning investigates the effect of mechanical load redistribution among failed and intact micro-structural bonds along fatigue crack growth to final crack at ...
