Crack paths in soft thin sheets
Fracture and Structural Integrity, 2019 Highly deformable materials (elastomers, gels, biological tissues, etc.) are ubiquitous in nature as well as in technology. The understanding of their flaw sensitivity is crucial to ensure a desired safety level.

Crack paths for mild steel specimens with circular holes in high cycle fatigue
, 2022 The most common current models for predicting the fatigue limit in notched solids use the stresses along a straight line, beginning at the notch root, to make the prediction.

Rolling effect in fretting fatigue test at the crack initiation stage [PDF]
, 2022 The aim of this work is to perform a detailed analysis of the cracks paths obtained in fretting fatigue tests with cylindrical contact but taking into account the presence of an unavoidable (due to the fretting device’s stiffness) small oscillatory ...

Crack paths in composite materials [PDF]
Engineering Fracture Mechanics, 2010 Composites are often exposed to harsh loading conditions. This may lead to crack formation and propagation. In this paper an algorithm is described to predict the path of pre-existing cracks in homogeneous materials, based on an incremental approach. The approach is shown to also deal with the highly heterogeneous behaviour of periodically distributed ...

Some practical crack path examples [PDF]
Fracture and Structural Integrity, 2007 It is well known that many engineering structures and components, as well as consumer items, contain cracks or crack-like flaws. It is widely recognised that crack growth must be considered both in designand in the analysis of failures.

Nonlinear dynamics of a rotating shaft with a breathing crack [PDF]
, 2011 In this paper, the effects of a breathing crack on the vibratory characteris- tics of a rotating shaft are investigated. A new, simple and robust model composed of two rigid bars connected with a nonlinear flexural spring is proposed.

Investigation of crack paths in natural fibre-reinforced composites [PDF]
Fracture and Structural Integrity, 2015 Nowadays, fibre-reinforced composite materials are widely used in many fields, e.g. automotive and aerospace. Natural fibres such as flax and hemp provide good density specific mechanical properties.

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
