Hybrid Method of Determining Strain-Rate-Dependent Constants for Johnson-Cook Failure and Plasticity Model.

In this article you may find information about the hybrid methodology for determining strain-rate-dependent constants for Johnson-Cook material model. This methodology is based on the use of experimental and numerical research. The methodology assumes the use of the Charpy hammer test with the notched and smooth samples for determining constants for plasticity and failure of the material. [ABSTRACT FROM AUTHOR]
