Nonlinear analysis using ANSYS


Hi ,


I am performing a nonlinear analysis (ANSYS) of GRP pipe which is subjected to diametral compression ,

 i am appling a line load in steps of 0.05 increments until load  reaches a maximum value  of 40kN in  20 steps 

i have got convergence till 13 steps but unable to get convergence in next further steps , i am getting error as LSSOLVE looping is stopped because solution is unconvergent and NCNV, 1set


 could any1 come forward and tell me how to fix this error so that i can get convergence 


Thank you all
