Hi AliGrailly, I can only assume that no one has responded because the answer is so apparent. The Eng-Tips forum was created to allow engineers to mentor other engineers, however as a prerequisite, everyone expects you to Google around or read the Code. The answer to your question can be...

You need to clarify what part of the MAWP reduction calculation you didn't understand. Simply put, Resultant Moment M and Axial Force W are converted into equivalent pressure Pm and Pr. The sum of Pm and Pr is then subtracted from Flange MAWP (taking effect of Moment factor Fm) at the design...

Thanks FEA way. That makes sense.

Fellow FE Analysts, I came across this article by SolidWorks which has put me in dilemma. SolidWorks Featured Paper It says the accuracy of all Simulation packages are same and depends on material, boundary conditions, etc. to which I agree. However, I know that in ANSYS, we have two solvers...

Adding to what XL83NL said, I used PV Elite SolidWorks plugin on SolidWorks 2018 and found that the import tool works well. It models the element systematically, for instance, flanges are Revolved around axis and bolt holes are Cut Extruded later. However, not all details are translated...

Hi, I assume you are using Main Menu>Preprocessor>Meshing>Mesh>Areas>Mapped>3 or 4 sided. Your geometrical area A1 seems quadrilateral. I'd recommend using Main Menu>Preprocessor>Meshing>Mesh>Areas>Mapped>By Corners and select the area and its corners . Alternatively, you can use AMAP, AREA...

Hi Houari Yahiaoui, You can find more information about pad flanges using the term Studded outlet flange. The link XL83NL provided is amazing :p

I second TGS4, the pressure thrust is required to balance the forces, and is a common practice where I work. One check you can do is don't apply any external forces and check for the membrane stress.

+1 to Erik, https://confluence.cornell.edu/display/SIMULATION/Home Here's another useful resource by the same author, Rajesh Bhaskaran, of Cornell University

Standard flanges should be used wherever possible. The cost of designing and fabricating a custom flange is expensive and should be a last resort. If a custom flange is required, and there is no alternative, then the procedures included in Mandatory Appendix 2 can be utilized for designing a...
