A displacement vector specifies the position of a point or a particle in reference to an origin or to a previous position. For example, a displacement field may be used to describe the effects of deformation on a solid body. Before considering displacement, the state before deformation must be defined. It is a state in which the coordinates of all points are known and described by the function: :$\backslash vec\_0:\; \backslash Omega\; \backslash rightarrow\; P$ where :$\backslash vec\_0$ is a placement vector :$\backslash Omega$ are all the points of the body :$P$ are all the points in the space in which the body is present Most often it is a state of the body in which no forces are applied. Then given any other state of this body in which coordinates of all its points are described as $\backslash vec\_1$ the displacement field is the difference between two body states: :$\backslash vec\; =\; \backslash vec\_1\; -\; \backslash vec\_0$ where :$\backslash vec$ is a displacement field, which for each point of the body specifies a displacement vector. ==See also== *Stress 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Displacement field (mechanics)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
