I have to make a nonlinear analysis of a cantilever beam with both horizontal and vertical load at free-end. The results of relations between vertical and horizontal displacement of free end are expected as shown in sample.pdf.
I have used load step increment with iteration based adapting with Arc-length control. However I did not get the results like figure shown in file sample pdf.
I need to modify filos command to make unloading scheme ( use snap-back behavior) in load steps. I tried to do it in long time, but I have gotten rigth results yet.
Could someone known about Arc-length control tell me what I should modify in filos file (filos.dcf) to get accuracy results. I have attached my input file, filos file and sample.pdf in attachment, please look at it.
Hope someone can help me. I would like to thank you in advance.
