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] Movement of rock along the fracture occurs in faults.
Anderson's theory of faulting; Aseismic creep; Fault block – Large blocks of rock created by tectonic and localized stresses in Earth's crust; Fault scarp – Small vertical offset on the ground surface; Joint – Type of fracture in rock; Mitigation of seismic motion; Mountain formation – Geological processes that underlie the formation of ...
Ernest Masson Anderson FRSE FGS (1877–1960) was a Scottish geologist. Ernest was born in Falkirk and educated at Falkirk High School and the High School of Dundee before attending the University of Edinburgh , where he received a B.Sc. in 1897, an M.A. in mathematics and natural philosophy in 1898, and a D.Sc. in 1933.
Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.
Low angle normal faulting is not explained by [[Anderson's theory of faulting|Andersonian fault mechanics]]. [8] However, slip on low angle normal faults could be facilitated by fluid pressure, as well as by weakness of minerals in wall rocks. Detachment faults may also initiate on reactivated thrust fault surfaces. [7]
The long development of the ACT-R theory gave birth to a certain number of parallel and related projects. The most important ones are the PUPS production system, an initial implementation of Anderson's theory, later abandoned; and ACT-RN, [7] a neural network implementation of the theory developed by Christian Lebiere.
The stress test can result in three outcomes: Pass, Partly Pass and Fail, based on the comparison of the quantified risks to acceptable risk exposure levels and a penalty system. Phase 3: Decision, during which the results of the stress test are analyzed according to the goal and objectives defined in Phase 1. Critical events (events that most ...
Stress triaxiality has important applications in fracture mechanics and can often be used to predict the type of fracture (i.e. ductile or brittle) within the region defined by that stress state. A higher stress triaxiality corresponds to a stress state which is primarily hydrostatic rather than deviatoric.
