Hi!
I am doing linit load analysis of 90 degree pipe elbows subjected 1)to out of plane moment alone and
2)Out of plane moment and internal pressure acting simultaneously.
I simulated th emoment by equal and opposite pressure on two halves of the pipe cross section.As there is no symmetry for out of palne loading I used full model of the elbow with staraight pipe of lenght 5D on both ends of the elbow to reduce end effects.
my problem is - what are the boundary conditions I should apply in the above two cases?
please help.
