Hi.

This is a material's problem.

I'm trying to simulate in FEA (Ansys) a part of a rectangular duct. this duct works with a flue gases qith elevated temparature (aporx 300°C).

Does anyone knows any standard (ASTM or similar) or any bibliography who gives data in form of tables or graphics that shows the variation of young modulus against temperature variation for materials?

Thanks

Martin
