FEA of Spade Installed on an Air Line
I am carrying out an FEA study on a 6mm thickness, 1894mm diameter spade which is to be installed to blind/isolate an air line. The material of the spade is ASTM A36 and the air pressure is 1.37bara. The essence of my study is to determine the optimum thickness that could be safely used to blind or isolate the line. The inside diameter of the circular duct is 1830mm, while the below highlighted faces (front & back) of the spade will be tightened (i.e. enclosed) between flanges of the duct.
I have created below 45deg model of the spade in ANSYS SpaceClaim and set it up in ANSYS Mechanical. The geometry face in blue below was where I applied the "Fixed" support, while the face along the circumference will be resting on the flange bolts.
I however feel the set up may be incorrect as the results are quite large and appearing unrealistic.
Please can someone assist to look at this and guide me on how to properly set this up to enable me obtain correct results within the capacity of the academic license.
Many thanks in anticipation.
