An indentation fatigue depth propagation law
Scripta Materialia, 2009Using both experimental and numerical studies, we show that, upon cyclic indentation with a flat cylindrical indenter, the steady-state rate of indentation depth propagation can be well characterized by a simple power-law function of the stress intensity range and the maximum stress intensity, which is qualitatively similar to the steady-state growth ...

A Fatigue Cracking Test for Tire Tread Compounds. Some of the Laws of Fatigue
Rubber Chemistry and Technology, 1936Abstract AN IMPORTANT factor in the service rendered by a tire tread is its ability to resist cracking. Cracking of tire treads in service may be classified into two kinds or phases—the initiation or start of cracks, and the growth of cracks or cuts once started—and the two phases must be differentiated. Nearly all tires in service soon develop

Proceedings of the Royal Society of Edinburgh, 1902
AbstractIn this paper a discussion of the mode of description of the linear paths in the (log b, n) diagram—described in previous papers—was given. It was shown that the assumption that fatigue was induced by oscillation of a wire enabled one, in almost all cases, to predict accurately the mode of description of these paths.

Hooke's law and fatigue limits in micromechanics
European Journal of Physics, 2001Scanning tunnelling microscopes can be used to detect transitions between reversible and irreversible deformations of materials. Since the occurrence of stress-strain hysteresis is a necessary condition for the generation of material defects, and the cumulation of defects is, in turn, the underlying cause of fatigue failure, the observation of non ...

Fatigue Laws via Functional Equations
Volume 4: Fatigue and Fracture; Fluids Engineering; Heat Transfer; Mechatronics; Micro and Nano Technology; Optical Engineering; Robotics; Systems Engineering; Industrial Applications, 2008In routine industrial design, fatigue life estimation is largely based on S-N curves and ad hoc cycle counting algorithms used with Miner’s rule for predicting life under complex loading. However, there are well known deficiencies of the conventional approach.

On the law of fatigue crack layer propagation in polymers
Polymer Engineering & Science, 1982AbstractA generalized theory of fatigue crack propagation in polymers is presented. The theory accounts for crack propagation through root craze extension accompanied by the dissemination of micro defects around the main crack thereby describing a crack layer (CL) system. In addition to the conventional crack length(l), the CL width(w) is introduced as

Laws of fatigue fracture of metallic materials
Metal Science and Heat Treatment, 2006A kinetic criterion of fatigue fracture of metallic materials is suggested and used for showing the existence of a single fatigue curve for cases of soft (with specified load amplitude) and rigid (with specified strain range in a cycle) loading for the stages of crack formation and propagation.

Elastic correction of fatigue crack growth laws
Fatigue & Fracture of Engineering Materials & Structures, 2019AbstractFatigue crack growth (FCG) is usually studied assuming that ΔKis the driving parameter. An effective ΔKis considered in the presence of crack closure. However, after crack opening, there is an elastic regime that does not contribute to FCG. The objective here is to quantify this elastic range of ΔK, ΔKel, for different loading conditions and ...

Fatigue & Fracture of Engineering Materials & Structures, 2020
AbstractThe present contribution investigates the crack‐size effects on Paris' law in accordance with dimensional analysis and intermediate asymptotics theory, which makes it possible to obtain a generalised equation able to provide an interpretation to the various empirical power‐laws available in the Literature.

New unified laws in fatigue: From the Wöhler’s to the Paris’ regime
Engineering Fracture Mechanics, 2007Generalizations and unification of the celebrated Paris' and Wohler's laws for fatigue crack propagation are derived by applying the recently developed quantized (or finite) fracture mechanics. In particular, three generalized Paris', Wohler's or unified laws are proposed and compared, demonstrating their applicability for predicting the life time of ...
