Calculating BMD for a hollow pipe beam

Submitted by nickg on

beams

I have tested steel pipe (as a beam) under lateral distributed loads. Longitudenal strain gages are on the top and bottom lines of the pipe. Could any one suggest to me how can I derive the bending moment distribution along the pipe. I have E, I , t (thickness, and r(radius) for the pipe.

 I have found a formula from litrature as follows : M = K.E.I

Where K = curvature = 0.5 * (ε_tension side - ε_compression side) / C (i.e the Half Section Depth, or pipe radius)

Greetings,

I'm working on thermal analysis of concrete filled steel tube columns.

I used all the guidance I could get  from the research papers, but I still didn't get the results I want.

In fact, all the job analysis I run ended up abrupted. 

I attached my abaqus work for your kind attention and perusal. 

Any suggestions and tips that might help me overcome my problem is more than welcome. Perhaps I could get some pointers whict part in my analysis is missing.

Thank you.

The auxiliary fields could be applied to the method for computation of SIFs for a dynamically propagating crack

Hi all,

Recently, I have read the paper "Dynamic crack propagation under mixed-mode loading- Comparison between experiments and X-FEM simulations" published in IJSS, 44 (2007), 6517-6534. I have met some questions on the choice of auxiliary fields for calculating the SIFs.  Could someone give me some details including the auxiliary velocity fields, the auxiliary displacement fields and the auxiliary stress fields. Thanks.

regards

sir/madam,

                i have modelled a curved section with one end fully constrained and to other end applied pull load, i am getting result in cylindrical co-ordinate system can i see the results in cartesian co-ordinate system
