| Abstract: | The paper aims to distinguish the two concepts of ＂element body＂, one used to analyze the force situation of a certain point, the other denoting the stress state of a certain point. It also discusses their characteristics, points out the essential difference between them, and puts forward a new expression for the latter one. |
