Nonrigid mechanics


Nonrigid mechanics is the general case of mechanics. It includes bodies with both internal and external motion. It is less concerned with discrete parts than with continuous bodies.

Nonrigid mechanics is the general case of mechanics. It includes bodies with both internal and external motion. It is less concerned with discrete parts than with continuous bodies.

This includes sections on deformable body mechanics, fluid dynamics, and wave mechanics. There may be other sections involved.

Wave mechanics

This section includes the study of mechanical waves and their propagation. It includes wave behavior in both deformable bodies and fluids, and in particlar the study of sound

Fluid mechanics

This includes the study of fluid statics, and includes ideal as well as real flow.

Deformable body mechanics

The description of deformable body mechanics is included here. This includes quantities of stress, strain, and elastic and plastic behavior.


The history of nonrigid mechanics dates in some respects to antiquity, although it was developed a little in classical and medieval times. Its greatest development has come in modern times. Developments in the 16th century are unclear, but the development of Newtonian mechanics in the 17th century was important. This has developed substantially in the 18th century, 19th century, and 20th century. Its future is obscure. Sociology including social structure and change, communities, and peoples of the world has some connection. Particular nations have contributed. Most of its development has come in Western civilization, but Asiatic peoples have been joining. African peoples and American Indian peoples have contributed little to it. Institutions including families, education, economics, government, and religion will be connected as the site develops. Culture including material culture and behavioral culture will be applicable. Conceptual culture including language, graphic arts, literature, mathematics, applied science, and philosophy will be useful. Anthropology including particular groups, human geography, human ecology, physical anthropology, demography, and social foundations is somewhat useful to norigid mechanics. Personal studies including biography may be useful. Psychology including behavioral elements, mind, behavior patterns, developmental psychology, mental disorders, personal studies, and social psychology will also be useful. The human body including form and appearance, life cycle, disease, body functions, and body systems demonstrates some application of nonrigid mechanics.
Biology including biohistory, ecology, systematics, organism biology, cell biology, and molecular biology also suggests applications. Earth science including geohistory, physical geography, atmospheric science, hydrospherc science, and geology also suggests applications. Astronomy including cosmology, galactic astronomy, stellar astronomy, and solar system astronomy provides more. Chemistry including systems, changes, and substances mostly involves applications of nonrigid mechanics.	Links to other sites: Not yet available
The structure of matter including subatomic physics, atomic physics, molecular physics, and bulk matter and exotic matter is fairly closely connected to nonrigid body mechanics. This does not depend much on quantum physics or on relativity, either the general theory or the special theory. Electromagnetism may be useful. Electrostatics including charge and charge distribution, electric force, field, flux, capacitance, and electrical properties of matter has some connection to rigid body mechics, through forces. Electric current including current definition, EMF, Resistance, DC Circuits, and AC circuits may also be connected. Magnetism including electric current elements, current assemblages, magnetic field, force, flux, and magnetic properties of matter has connections to nonrigid mechanics. Optics including electromagnetic waves, geometric optics, physical optics, quantum optics, and the electromagnetic spectrurm may be useful. Thermodynamics including nonclassical thermodynamics, classical thermodynamics, and statistical mechanics may be useful. This makes some use of gravitation, including nonrigid celestial mechanics, rigid body celestial mechanics, particle celestial mechanics, and surface gravitation. Nonrigid bodies also make heavy use of rigid body mechanics. Dynamic systems and static systems can be connected. Rotational dynamics including mass distribution, linear and angular momentum, torque, and cases of motion is useful. Rigid bodies and motion include extended bodies, location and orientation, linear and angular velocity, and linear and angular acceleration can be considered. Nonrigid bodies depend heavily on particle mechanics. Particle systems, including simplified systems, particle interactions, and system properties are sometimes highly useful in advanced mechanics. Energetics with its concepts of power, mechanical energy, and work is also needed. Concepts of kinetics including types and cases of force, force concepts, momentum, and mass are also fundamental. Kinematics and elementary concepts of types and cases of motion, acceleration, velocity, and position, and particle description can be connected.
