Layered inversion method for dynamic constitutive model of the 18CrNiMo7-6 alloy steel surface-modified layer

Jixie qiangdu
To address the issue of characterizing static and dynamic mechanical behaviors of the surface-modified layer (SML) in 18CrNiMo7-6 alloy steel, a layered inversion method for the Johnson-Cook (J-C) constitutive model of SML was proposed.
