Glossary (глосарій)

It can be stated as follows: If a set of self-equilibrating loads are applied on a body over an area of characteristic dimension d, the internal stresses resulting from these loads are only significant over a portion of the body of approximate characteristic dimension d. Note that this principle is rather vague, as it deals with 'approximate' characteristic dimensions. It allows qualitative rather that quantitative conclusions to be drawn. An important application of Saint-Venant's principle deal with end effects in bars and beams.
