Effective stress intensities in stress corrosion cracking

International Journal of Fracture, 1976
The phenomena of branching and blunting of stress corrosion cracks are reviewed and their effects demonstrated for a martensitic steel. The stress intensity that a crack can sustain is proportional to the square root of its tip radius, so that blunt cracks require a higher apparent stress intensity.

A review of stress in the intensive care unit

Intensive Care Nursing, 1987
Abstract The demands of caring for critically ill patients can be extremely stressful. In their everyday work nurses confront suffering, grief and death in a way that few other professional groups do. Current stress research, exploring the nurse and her reaction to work in the intensive care unit (ICU), has discovered a number of stressors that can ...

Nursing Stresses in the Intensive Care Unit

JAMA: The Journal of the American Medical Association, 1969
To the Editor:— The report of the Committee on Nursing, "Stresses on the Nurse in an Intensive-Care Unit" ( 208 :332, 1969), recognizes a new problem incurred by nursing staff concurrent with the development of intensive-care units (ICU). A case of paroxysmal auricular tachycardia and a case of acute duodenitis in the intensive-care unit of Clara ...

Intensive Stress?? Caring under pressure

Journal of The Royal Naval Medical Service, 1991
Abstract This article is based on a survey of the intensive care nursing staff at RNH Haslar and RNH Stonehouse. It examines individuals response to external stressors and was undertaken as part of a project for the Health Education Certificate Course. The survey took place during December 1989 and January 1990.

Parental stress in paediatric intensive care

British Journal of Nursing, 1993
Family-centred care has become an important concept in paediatric nursing. However, there are factors within the paediatric intensive care environment that act as barriers to implementing family-centred care and maintaining the caring relationship between the parents and their critically ill child.

Stress intensities at notch singularities

Engineering Fracture Mechanics, 1997
In the context of linear elasticity, a stress singularity of the type Knrδ (δ < 0) may exist at re-entrant notch corners, with an intensity Kn. The magnitude of the intensity, referred to here as the notch stress intensity, characterizes the stress state in the region of the notch tip. We determined Kn for two mode I-type specimens that are proposed to

Stress intensity in viscoelastic contacts

Tribology Letters, 2000
Dynamic mechanical contacts with nanometer-to-micrometer dimensions are important in scanned probe microscopy, ultra-low load indentation, microelectromechanical systems, compact discs, etc. The response of these contacts is poorly understood if they involve adhesive viscoelastic materials, such as polymers and self-assembled monolayers.

The linguistic relevance of intensity in stress

Lingua, 1955
Abstract The authors show by means of several arguments and experiments that in so-called dynamic stress intensity cannot be considered as a factor, regardless whether this term is taken in an acoustic or in an articulatory sense.

Evaluation of stress intensity factors

Journal of Strain Analysis, 1975
Some of the more useful methods of evaluating stress intensity factors are presented in a concise form. The stress intensity factor is defined and compared with the more familiar stress concentration factor. The shape factor, the parameter which characterizes the shape of the crack, the orientation of the crack and the proximity of other boundaries, is

Stress Intensity Factors for a Linear Stress Distribution

2003
The stress intensity factor for an edge crack of length a in a semi-infinite plate subjected to a pair of equal and opposite concentrated forces at a distance b from the plate edge (Figure 1) is given by [1] $$ K'_I = \frac{2} {{\sqrt \pi }}\frac{{1 + F\left( {{b \mathord{\left/ {\vphantom {b a}} \right.
