Types of faulting. Anderson's theory of faulting, devised by Ernest Masson Anderson in 1905, is a way of classifying geological faults by use of principal stress. [1] [2] A fault is a fracture in the surface of the Earth that occurs when rocks break under extreme stress. [3]
The diathesis-stress model, also known as the vulnerability–stress model, is a psychological theory that attempts to explain a disorder, or its trajectory, as the result of an interaction between a predispositional vulnerability, the diathesis, and stress caused by life experiences.
Transactional Model of Stress and Coping of Richard Lazarus Richard S. Lazarus (March 3, 1922 – November 24, 2002) was an American psychologist who began rising to prominence in the 1960s. A Review of General Psychology survey, published in 2002, ranked Lazarus as the 80th most cited psychologist of the 20th century. [ 1 ]
In regards to general stress, research has explored how the loss of resources impacts the levels of one’s stress. [16] COR has primarily been studied within the burnout and job fields, as the following meta-analyses will demonstrate. There is currently no meta-analyses on COR within other areas of stress research.
Claims about the nature of stress, emotion, and social behaviour, are traditionally studied via peripheral indices of arousal such as heart rate, cortisol level and skin conductance. [1] Polyvagal theory champions the measurement of vagal tone as a new index of stress vulnerability and reactivity, including in populations with affective disorders .
Rankine's theory (maximum-normal stress theory), developed in 1857 by William John Macquorn Rankine, [1] is a stress field solution that predicts active and passive earth pressure. It assumes that the soil is cohesionless, the wall is frictionless, the soil-wall interface is vertical, the failure surface on which the soil moves is planar , and ...
As an example, the stress state of a steel beam in compression differs from the stress state of a steel axle under torsion, even if both specimens are of the same material. In view of the stress tensor, which fully describes the stress state, this difference manifests in six degrees of freedom , because the stress tensor has six independent ...
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.
