Problem description

Material:

Linear elastic, Young's modulus = 10⁶, Poisson's ratio = 0.3.

Boundary conditions:

; ; .

Step 1

A concentrated moment loading equivalent to a distributed moment loading M of 6402 is applied on top face CD.

Analytical solution:

Twist

= 0.01 (on top face CD).

Stresses

Results and discussion

All elements yield the analytical solution.

The *SECTION FILE and *SECTION PRINT output requests are used in some of the input files to output accumulated quantities on the face CD. The area of the face is 3.142.
