This report describes current progress in the development of a predictive model for fatigue crack growth under variable amplitude loading [1,2]. The work is based upon the inclined strip-yield superdislocation representation of crack tip plasticity, an extension of the idea of Atkinson and Kay [3].
AbUmct-S&ess and strain Md of a propagating fatigue crack and the resulting crack opening and &sing behavior were anaiyscd. It was found that a propq&g fatigue crack was closed at ten& external Ioads due to the cyclic&y induced residual stresses. Strain range v&e AC, in the vicinity of the crack tip
## a b s t r a c t As is well-known, strength of materials is influenced by the specimen or structure size. In particular, several experimental campaigns have shown a decrease of the material strength under static or fatigue loading with increasing structure size, and some theoretical arguments hav
