  • Deformation (mechanics) — This article is about deformation in mechanics. For the term s use in engineering, see Deformation (engineering). Deformation in continuum mechanics is the transformation of a body from a reference configuration to a current configuration.[1] A… …   Wikipedia

  • Deformation (engineering) — This article is about deformation in engineering. For a more rigorous treatment, see Deformation (mechanics). Compressive stress results in deformation which shortens the object but also expands it outwards. In materials science, deformation is a …   Wikipedia

  • Discontinuous Deformation Analysis — (DDA) is a type of discrete element method originally proposed by Shi in 1988. DDA is somewhat similar to the finite element method for solving stress displacement problems, but accounts for the interaction of independent particles (blocks) along …   Wikipedia

  • Vitesse de déformation — En mécanique des milieux continus, on considère la déformation d un élément de matière au sein d une pièce. On s attache donc à décrire ce qui se passe localement et non pas d un point de vue global, et à utiliser des paramètres indépendants de… …   Wikipédia en Français
