i have for maraging steel.

Ahmed Jubara

As I know, the R-curve depends on the specimen dimensions (especially the x-axis). If you would like to get the SERR you could find it for Al-2024 as a material property.

Mohammad Nejati

thank you so much Mr Pany but I'm looking for R-curve for Al 2024. anyway thanks for consideration

Thank you Mr Jubara. As you mentioned R-curve obtained experimentally.

Do you know how I can find material property of Al 2024-T3 like J-IC and R-curve(or load-displacment data from experimental test )?

You are welcome Mohammad,

There are many ways, for instance, SENT and DCB tests are used to obtain the load-displacement curve.

Then, a data reduction scheme, such as CBT (beam theory) or CBBM (compliance-based beam method) or any, used to obtain the R-curve.

Finally, the plateau region of the R-curve represents G_IC.

I'm sure that you can find G_IC directly from the literature for your alloy.

Good luck..
