What stress analysis software
Thread Content
This post was last edited by Li Jia Xiao Nu on 2012-5-28 at 19:42. Dear fellow sailors, apart from ANSYS, are there any other stress analysis software used in design institutes? (Just in terms of pressure vessel design), does what design institutes refer to as stress analysis mean performing calculations in accordance with GB150 for the entire vessel, while carrying out stress analysis on specific areas?
There are also NX Nastran, RedArrow VAS, and ALGOR. It seems that the Standardization Committee also has a stress analysis system, but ANSYS is the most well-known and is used by the largest number of people. I’m not sure what you mean by \"stress analysis\" in general terms; the failure criteria for stress analysis differ from those for design based on rules. SW6 can also be used to perform simple stress analysis on pipes
In our country, analytical methods are used for analysis and design, but numerical analysis methods are also permitted; there are many such programs such as ANSYS, ABAQUS, MSC, and ADINA. If you’re very skilled, you can write your own programs using FORTRAN or MATLAB. In China, ANSYS is commonly used for the analysis and design of pressure vessels; if you don’t use it, people may consider you unconventional, but that doesn’t mean ANSYS is the best option.
Learn ANSYS. .
GB150 uses the analytical method, and all those formulas in JB4732 are also based on the analytical approach; however, the stress analysis discussed these days actually makes use of the finite element method, which is a numerical technique. There are many software options; among the major general-purpose finite element analysis software are ANSYS, Abaqus, COMSOL, Algor, and MSC. Only a small part of the pressure vessel is used. ANSYS has grown to an enormous scale nowadays; it has acquired companies such as CFX, Fluent, Ansoft, etc. It is extremely powerful, with robust coupling capabilities.
There is also a dedicated finite element program for pressure vessel nozzles
