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.

Calculating BMD for a hollow pipe beam

Submitted by nickg on

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)

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
