Will home owners get that sinking feeling this summer?



Are we in for a summer of cracked buildings? It all depends on the weather. Research from the British Geological Survey (BGS) has highlighted the importance of rainfall and temperature on the incidence of clay shrink-swell, a precursor to subsidence, in the UK. For many, the cool, wet conditions we have experienced so far this summer may be just what is needed to keep their house in order.

non linear analysis of a cylinder

Submitted by shabber hussain on
convergence problems

Hi...

I am working on post buckling of a cylinder in ANSYS. I have included imperfections using NLGEOM command. I applied a load which is slightly higher than eigen value buckling analysis and i am using displacement controlled analysis using arc length method. I am getting the following error after certain time

"solution not converged

Arc length  value has reached its minimum allowed value

Run terminated"

Can anyone please help me how to resolve this issue.....

ANSYS - Nonlinear analysis -Deflections and the loads

Submitted by senthil1947 on

Hi All,

I would like to apply the below:

1) Apply a prescribed displacements to a cantilver beam 

2) Save the deformed configuration

3) Apply the loads on the deformed configuration

4) calculate the final deflections 

How to do it in ANSYS or the best way to do it

Thanks in advance
