Dear All

For flange leakage analysis in Equivalent Pressure method,we have to input the axial force, circumferential moment & longitudinal moment.
If the axial force is force is compressive we can input zero, if it is tensile force we have to input the value.
My question is how can we identify whether the force acting at particular point is tensile force or compressive force.

Please clarify.

Regards
GS

Dear G.S,

z. . . >x (axis) ; 10-------20-------30 (elements run)

local force report
10 fx = 1000 N
20 fx = -1000 N

20 fx = 1000 N
30 fx = -1000 N

to know in node 20 (compress/tension)
sketch the direction of forces acting on the element 10 to 20
(+1000)====>10---------20<======(-1000) (compress at node 20)

or

sketch the direction of forces acting on the element 20 to 30
(+1000)====>20---------30<======(-1000) (compress at node 20)

Use pen and paper don't keep in brain.
