Mohammed Al-Nehari 阿里 You can refer to this paper for the derivation of Johnson-Cook parameters. It is highly detailed in deriving the D constants step by step.

In short solely tensile test will not help you to get the damage parameters. You will need to prepare notched samples and their associated tests.
