Continuum mechanics

Continuum mechanics is a annex of mechanics that deals with the assay of the kinematics and the automated behavior of abstracts modelled as a connected accumulation rather than as detached particles. The French mathematician Augustin Louis Cauchy was the aboriginal to codify such models in the 19th century, but analysis in the breadth continues today.

Modelling an article as a continuum assumes that the actuality of the article absolutely fills the amplitude it occupies. Modelling altar in this way ignores the actuality that amount is fabricated of atoms, and so is not continuous; however, on breadth scales abundant greater than that of inter-atomic distances, such models are awful accurate. Fundamental concrete laws such as the attention of mass, the attention of momentum, and the attention of activity may be activated to such models to acquire cogwheel equations anecdotic the behavior of such objects, and some advice about the accurate actual advised is added through a basal relation.

Continuum mechanics deals with concrete backdrop of debris and fluids which are absolute of any accurate alike arrangement in which they are observed. These concrete backdrop are again represented by tensors, which are algebraic altar that accept the appropriate acreage of getting absolute of alike system. These tensors can be bidding in alike systems for computational convenience.
