A NOTCH INTENSITY FACTOR APPROACH TO THE STRESS ANALYSIS OF WELDS
Fatigue and Fracture of Engineering Materials and Structures, 1998In the context of linear elastic stress gradients that are present in welded joints, a stress field approach based on notch stress intensity factors is presented with the aim of describing stress distributions in the neighbourhood of weld toes, since fatigue strength is dependent on such distributions.

Stress and stress disorders during and after intensive care
Current Opinion in Anaesthesiology, 2004We provide an overview of the multilevel/multidimensional approach to stress and stress disorders, and integrate research findings into the intensive care context. Recent findings are discussed within the context of well studied biopsychological theories of stress and stress disorders.The stress response must be viewed as a process.

Symptom Intensity and Life Stress in the City
Archives of General Psychiatry, 1974Association between symptom severity and recent life stress has been documented repeatedly. We report relationships among selfrated symptom intensity, life stress of recent undesirable events, and demographic characteristics in a probability sample of urban adults. Higher symptom intensities were reported by women, the unmarried, whites, persons under

Journal of Applied Mechanics, 1983
In this paper the concept of the stress intensity factor, the underlying mechanics problem leading to its emergence, and its physical relevance, particularly its relation to fracture mechanics are discussed, the reasons as to why it has become nearly an indispensable tool for studying such important phenomena as brittle fracture and fatigue or ...

Stresses on the Nurse in an Intensive‐Care Unit
AORN Journal, 1969Stresses identified in this communication are those observed in nurses assigned to a fourbed unit in the Clinical Center, National Institute of Health, Bethesda, Md. This intensive-care unit (ICU) is designed to facilitate the recovery of individual patients after general and radical surgical procedures, but not open-heart or neurological operation ...

Stress intensity factors in the presence of contact stresses
Engineering Fracture Mechanics, 1995Abstract In this paper, a loaded tolerance-fit pin in a cracked or uncracked lug is studied. Both symmetrical and non-symmetrical cracks are considered. A symmetrical contact problem due to symmetrical cracks, can be solved automatically. However, non-symmetrical problems can be solved only by re-meshing at each load step if a consistent and smooth ...

Effective stress intensities in stress corrosion cracking
International Journal of Fracture, 1976The 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.

Intensive Stress?? Caring under pressure
Journal of The Royal Naval Medical Service, 1991Abstract 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.

A review of stress in the intensive care unit
Intensive Care Nursing, 1987Abstract 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 ...
