Dear all,
if I have vessel nozzle calculation result from FEA shell model, how I caculation the stiffness for input into piping model in CAESAR II (Vessel and Nozzle joint in Cnode)? is the following step correct?
from the nozzle vessel joint FEA result from each direction: Stiffness =(Nx/tx,Ny/ty,Nz/tz,Mx/ax,My/ay,Mz/az),in where Nx,Ny,Nz, Mx,My,Mz is force or momnet in joint point, tx,ty,tz,ax,ay,az is translation or rotation in joint point.
do I need multiply the related beam stifness in the above stiffness caulcation?
thank you for your comment and advice.
Best Regards
