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 ...

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 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.

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

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.

Stress Intensities at Spot Welds

International Journal of Fracture, 1997
The stress intensities (notch stress, stress intensity factors and J-integral) at spot welds under typical loads of tensile-shear, cross-tension and coach-peel are derived as a number of simple formulas on the basis of an analytic solution where the stress intensities at spot welds are generally determined by the stresses around the spot welds and of ...

Summary of Stress-Intensity Factors

1996
Abstract The stress-intensity concept is based on the parameter that quantifies the stresses at a crack tip. This article summarizes some stress-intensity factors for various crack geometries commonly found in structural components. Through-the-thickness cracks may be located in the middle of a plate; at the edge of a plate; or at the

A Stress Intensity Factor Tracer

Journal of Applied Mechanics, 1985
A new optical method, Stress Intensity Factor Tracer (SIFT), has been developed. The device measures continuously the real-time stress intensity factor variation, K1(t), of a moving crack tip using a single, stationary photodetector. The method uses the fact that any variation in K1(t) leads to a change in the intensity of light, I(t), impinging on a ...
