hi,i have been doing non-linear buckling analysis using STATIC RIKs method
my model specification: length:65 metre, dia=2.85metre,thickness=0.38meter
and i am having the following doubts:
1.i have done Eigen value buckling analysis first and got the mode values..but for getting the mode shapes which load value i have to apply????(whether calculated euler buckling load value)
2.i have given imperfection as 0.0038 i.e..,10% of thickness value is it correct????
3.how to calcuate critical buckling load from abaqus??
4.my model containd rack teeth,,but i didnt model that one..coz making shell is difficult...can i solve using solid elements??????
how can i conclude????
can anyone help me..
Thanks in advance...
