Question

Each triangle formed by three nodes and three sides is called a ______

(a) Node

(b) Force matrix

(c) Displacement vector

(d) Element

This question was posed to me during an interview.

The query is from Two Dimensional Problems in division Two Dimensional Problems using Constant Strain Triangles of Finite Element Method

Answer 1

Right choice is (d) Element

The best I can explain: An element is a basic building block of finite element analysis. An element is a mathematical relation that defines how the degrees of freedom of a node relate to next. In discretization of 2D element each triangle is called element.
