Question

In two dimensional modeling, elemental volume is given by ____

(a) dV=tdA

(b) dV=dA

(c) f=[fx,fy]^T

(d) Trussky program

The question was asked in quiz.

I need to ask this question from Two Dimensional Problems in portion Two Dimensional Problems using Constant Strain Triangles of Finite Element Method

Answer 1

The correct answer is (a) dV=tdA

To explain: In mathematics, a volume element provides a means for integrating a function with respect to volume in various co-ordinate systems such as spherical co-ordinates and cylindrical co-ordinates. Then elemental volume is given by

dV=tdA.
