Dear sir,
i have read the paper concerning "modeling large D/d Tees"in the COADE MECHANICAL ENGINEERING NEWS-december 1998, i am not very clear about one
things: the branch SIF should be applied at the surface of header(node 2025)-as the paper recommended in Figure4, but is it needed to apply SIF
at node 2020 at the same time,which mean to apply sif not only at node 2025 and but also at node 2020? i think it is needed ,but i am not very clear about it? can anyone give me some advice.
the second question, usually the tee wall thickness is thicker than the run pipe of header and the branch pipe, is it reasonable to specify the thickness of the tee(which are thicker than run pipe of header and branch)on the element 2025-2020,2020-2030,and 2025-2026( i add node 2026 between node 2025 and 2200,the length of element 2020-2025+element 2025-2026= Tee hight)
then add SIFs at node 2010,2020,2030,2025,2026.
the SIFS added at node 2010,2030 and 2026 are for wall thickness change.
THANK YOU FOR YOUR TIME!
