Considering the effects of the numbers and diameters of film cooling holes, the Low Cycle
Fatigue (LCF) performances of Ni-based single-crystal superalloy plate specimens were …

Prediction of how cracks nucleate and develop is a major concern in fracture mechanics.
The purpose of this study is to provide an overview of the state of the art on fracture …

The critical distance inverse search procedure, recently proposed by the authors (Santus et
al., 2018), was experimentally applied in this work to 42CrMo4+ QT steel and 7075-T6 …

Notches, local stress raisers within structural components, are one of the most important
locations for fatigue crack initiation. It is well known that fatigue is governed by the effective …

The critical distance length should in principle be deduced from the plain specimen fatigue
limit and the threshold stress intensity factor range. However, the threshold range is difficult …

This paper provides a methodology for the prediction of fracture loads in notched materials
that combines the equivalent material concept with the theory of critical distances. The latter …

Abstract The Strain Energy Density (SED) fatigue criterion is based on a material control
radius. The value of this length is therefore required for an accurate assessment of the …

The theory of critical distances is based on the definition of a material-dependent length L.
Here, we investigate the statistical properties of L deduced from the crack threshold or a …

An optimized V-notched specimen is proposed for the determination of mode III, or torsional,
critical distance. Numerical procedures are provided for the inverse determination of this …

The results of theoretical and experimental studies of brittle and quasi-brittle fracture of
plaster plates containing a circular hole and subjected to non-uniformly distributed …
