Many of the expertises suggested Arclength method is best method for nonlinear buckling analysis. I used Arclength method for my analysis with material nonlinearity and geometric imperfection. Anyway I have get a converged solution for structure with high geometric imperfection(<strong>More than 10%<\/strong>). If I use very small amount of geometric imperfection <strong>(like 0.5,1and 2 percen<\/strong>t), It does not converged to a solution. I have tried with maximum number of substeps, still not converging.<\/p>\n<p><\/p>\n<p>Also raised many times this problem in this community but no one respond.<\/p>\n<p><\/p>\n<p>I have attached my file of 0.1% geometric imperfection with this.
