## Abstract Bars cyclically loaded by oppositely concentrated forces via rollers are appropriate test specimens for the determination of fatigue under contact loading. The contact strengths and numbers of cycles to failure under contact loading were determined for coarseβgrained alumina. From theor

## Abstract A method utilizing expansion of a diaphragmβtype film specimen was developed to study __in vitro__ biodegradation of poly(etherurethane urea) (PEUU) under conditions of dynamic loading (fatigue). A finite element model was used to describe the strain state, which ranged from uniaxial at
A statistical approach to fatigue fracture under constant load is presented. Crack initiation due to detrimentally-acting external factors is considered, with a time-dependent rate assumed for an ensemble of growing stochastically-independent fatigue cracks. For crack increments under cyclic loading
A stochastic model describing fatigue crack growth under random overload peaks is presented. A Poisson flow of overloads superimposed on a base-line constant-amplitude cyclic load is considered. Under the above assumptions the total retardation time is presented as a stochastic process governed by t
