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.

Rather than causing us to store anger in our back, or fear in our stomach, stress triggers a dynamic whole-body response—and it happens not just when people repress their emotions, but even if ...
Stress is wear and tear on the body in response to stressful agents. Hans Selye called such agents: stressors, which are physical, physiological or sociocultural. Stress-related disorders differ from anxiety disorders, and do not constitute a normative concept.

The ability of a material to withstand compressive stresses without failing is known as its compressive strength. When an object is subjected to a force in a single direction (referred to as a uniaxial compression ), the compressive stress is determined by dividing the applied force by the cross-sectional area of the object.
