Johnson-Cook's model is employed as the constitutive law for the workpiece material.
However, the machining process of metal cutting is quite complex, relating to physics, mechanics, elastic-plastic theory, metal material, thermology and superficial science (tribology) and so on.
Material Model.
Johnson-Cook model describes material yielding flow properties of the cutting region more exactly.
