Question about the meshfree analysis when two types of materials coexist in the background cell

Hi, everyone!

I will employ the meshfree method in order to analyze the composite model including the spherical filler and matrix.

However, if the background cells are regular reluctantly, there will be background cells where two types of materials coexist.

In this case, I don't know how to calculate the integral form, K=int_V B'CB dV, numerically.

i want to model a single pile whith surrounding soil in abaqus. my problem is about:

1)step mudulus: how i must define step mudulus to obtain a time history and spectral(frequency) displacement response.

2)how i can apply elcentro spectrum in abaqus. i dont know nothing about this.

thanks

 

Calculating BMD for a hollow pipe beam

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.
