I have done an analysis using COSMOSWorks on a steel
structure we are designing.
One of my colleuges has asked how COSMOS defines compressive strength of the material when it is not defined in the material properties.
The material we are using is AISI 304, from the COSMOSWorks material library. My VAR has been unable to help with this.
Any assistance or advise would be very much appreciated.

So... in answer to your question, COSMOSWorks doesn't define Compressive Strength because it doesn't really care what it is to do its job. That said, 304 is an extremely ductile SS at room temps and ductile materials tend to have the same compressive properties as tensile properties (a characteristic called 'symmetry') While the data gnome who typed all these properties in many many years ago may simply have neglected to enter a compressive strength, it is equally likely that he assumed compressive strength was equal and opposite to tensile and left it blank intentionally. I opened 2 references I keep on my desk and neither list a compressive strength for 304.
Make sense?
