Failed shut-down: the inability of the body to shut off while stress accelerates and levels in the body exceed normal levels, for example, elevated blood pressure. Inadequate response: the failure of the body systems to respond to challenge, for example, excess levels of inflammation due to inadequate endogenous glucocorticoid responses.
In mathematical terms, failure theory is expressed in the form of various failure criteria which are valid for specific materials. Failure criteria are functions in stress or strain space which separate "failed" states from "unfailed" states. A precise physical definition of a "failed" state is not easily quantified and several working ...
Within the branch of materials science known as material failure theory, the Goodman relation (also called a Goodman diagram, a Goodman-Haigh diagram, a Haigh diagram or a Haigh-Soderberg diagram) is an equation used to quantify the interaction of mean and alternating stresses on the fatigue life of a material. [1]
For example, cardiac decompensation may refer to the failure of the heart to maintain adequate blood circulation, after long-standing (previously compensated) vascular disease (see heart failure). Short-term treatment of cardiac decompensation can be achieved through administration of dobutamine , resulting in an increase in heart contractility ...
Schematic overview of the classes of stresses in plants Neurohormonal response to stress. Stress, whether physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. [1] When stressed by stimuli that alter an organism's environment, multiple systems respond across the body. [2]
As well as physical pressure, mental stress from the workplace can cause karoshi. [12] [13] People who die by suicide due to mental stress are called karōjisatsu (過労自殺). [12] The ILO also lists some causes of overwork or occupational stress that include the following: All-night, late-night or holiday work, both long and excessive hours.
The two plastic limit theorems apply to any elastic-perfectly plastic body or assemblage of bodies. Lower limit theorem: If an equilibrium distribution of stress can be found which balances the applied load and nowhere violates the yield criterion, the body (or bodies) will not fail, or will be just at the point of failure. [2] Upper limit theorem:
Stress is a bimonthly peer-reviewed medical journal covering research on stress in terms of: the mechanisms of stressful stimulation, the physiological and behavioural responses to stress, and their regulation, in both the short and long term; adaptive mechanisms, and the pathological consequences of stress.
