How to simulate torsion of cylinder in ANSYS?

I want to model torsion of a homogeneous hollow cylinder in ANSYS. I changed to cylindric coordinate system also. But each time I run the program  the result is that of bending. I have attached the mac file and output file for reference. Please advise.

I want to understand how beams are classified in terms of short and long beams. What is the criteria to classify them. Please suggest any reference.

 

TIA

ANSYS HELP NEEDED

Mon, 2008-03-10 08:47 - sspadhee

I am analysing a beam made of composite material in ANSYS. loding is axial and is applied on the end face. Other end is fixed. I want the deformed face  to be parallel to undformed face. no out of plane warping or deformation. How to do it ? I know applying foce and displacement constraints simultaneously is not possible(and is not wise) but is there a way  ?

What is the difference between RVE and Unit Cell ?

Tue, 2008-02-19 03:47 - sspadhee

I have been working in composites for sometime now. In the literature I have found that the words  "Representative Volume Element" (RVE) and "Unit Cell" (UC)  are  used frequently.  Some  authors treat them differently and some treat them  same. I am little bit confused can anyone PLEASE clarify the situation or suggest some good papers to read.

 

Thanks In Advance.
