2, Gauthier-Villars, Paris (Reproduction Bibliothe ́que Nationale de France, 1995). Relating or pertaining to the field of geodynamics. A broad, multidisciplinary branch of geophysics that investigates the causes and consequences of the forces acting on and inside the solid Earth and the rock movements and deformations they produce. Concepts for reference frames in geodesy and geodynamics - The reference directions The paper discusses a study that establishes a reference frame, moving with the earth (in some average sense), in which the geometric and dynamical behavior of the earth can be monitored, and whose motion with respect to inertial space can also be determined.

The orientation tensor and the yield stress are usually modelled to include a simple damage evolution that relates to the work expended in deforming the material at yield. Typically, \(\eta\) varies by several tens of orders of magnitude over the typical temperature ranges expected between the Earth’s surface and interior. \(\Lambda\) is a structural tensor that represents the orientation of the plastic deformation relative to the applied stress and \(\lambda\) is a scalar multiplier that is computed to satisfy the stress conditions at yield. Where \(\mu\) is the elastic shear modulus and \(\eta\) is the shear viscosity (both of which may vary with temperature and composition). Terzaghi, K., 1943, Theoretical Soil Mechanics.

Nevertheless, many researchers believe that these facts can be explained as the result of certain, often hypothetical, processes that are based on the simple fundamental laws of physics and of chemistry. The Stokes momentum equation neglects inertia but includes an additional term on the right hand side that. The facts adduced by geological and geophysical exploration techniques are extremely complex. The simplest template set of equations for solid-Earth dynamics cover mass, momentum and heat conservation in a highly viscous fluid allowing for additional effects due to elasticity and plasticity.

Now, however, the term has been broadened to include the discussion of all dynamic processes that occur within and on the solid Earth. flex.h File Reference Go to the source code of this file. In those days, the term more specifically designated the interrelationship of the dynamics of the Earth with cosmic effects-i.e., phenomena such as the tides of the solid Earth. In this instance, the term geodynamics has changed its accepted meaning somewhat since Love (1911) wrote his celebrated treatise on the subject. Geodynamics is that part of the earth sciences in which an attempt is made to explain the observed facts about our globe in terms of fundamental mechanical (dynamic) principles.
