These material properties depend too strongly on the exact alloy composition, the heat treatment etc. to be able to answer this.

Hi Asma, it depends on what type of Copper you are talking about. There are many literature articles used copper properties in FE analysis. You can find them online. Better, if you have any experimental data of your copper, you can translate the stress-strain curve as the input parameters of Abaqus and utilize the properties for FE analysis. If you need detail information, contact me. Thanks!!

It is a Beryllium copper (ASTM B194), Cu 97.75, Be 2.0 and Ni 0.25

The ASTM should specify at least the yield strength
