摘要
The peculiarities of the use of the Jaumann and Green-Naghdi corotational derivatives were investigated for modeling deformation processes in isotropic and anisotropic materials under shock loading. Using the aluminum alloy 2024 as an example, it has been shown that taking into account the anisotropy of mechanical properties affects the values of the Jaumann and Green-Naghdi corotational derivatives upon returning the alloy to an unstressed state. It was proposed to use the combination of the Jaumann and Green-Naghdi corotational derivatives to increase the accuracy in numerical calculations of the stress tensor components.
