A review on Johnson Cook material model

To design and optimise process parameters in the metal forming industry, it is necessary to have a consistent and realistic representation of material behaviour where strain, strain rate, and temperature have an effect on the material flow stress. This paper examines various approaches that are employed in calculating the Johnson Cook material constants. Split Hopkinson-bar methodology and universal tensile tests were used to determine the material constants related to Johnson Cook material and failure models. These models were used in numerical simulations to facilitate design optimization and reduce experimentation costs. Johnson Cook material models were employed in various simulation software’s like ABAQUS, LS-DYNA, and DEFORM 3D to simulate metal turning, milling, and forming operations.
