Question

In two dimensional modeling, traction force is denoted as ____

(a) Row vector

(b) T=[Tx,Ty]^T

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

(d) σ=Dε

The question was asked in homework.

This key question is from Two Dimensional Problems topic in portion Two Dimensional Problems using Constant Strain Triangles of Finite Element Method

Answer 1

Correct choice is (b) T=[Tx,Ty]^T

Easy explanation: Traction or tractive force is the force used to generate motion between body and a tangential surface, through the use of dry friction, through the use of hear force. Tractive force is defined as

   T=[Tx,Ty]^T
