• Predicting the coefficient of restitution of impacting elastic-perfectly plastic spheres (2010, methodology): “While the current results appear to partially agree with a recent analysis by Kogut and Etsion [27], which suggests that strain hardening actually plays a minor role, this and other works find that the strain rate (time) effect does appear to be meaningful.”
• A statistical model of elasto-plastic asperity contact between rough surfaces (2006, neutral): “In their work a finite element analysis is performed that produced results appreciably different than the similar Kogut and Etsion (KE) model [4].”
• A Review of Elastic–Plastic Contact Mechanics (2017, methodology): “With the development of the finite element method and access to computational resources, modeling capabilities were advanced by many researchers, including Li and Thorn-ton [44], Wu et al. [45], Kogut and Etsion [93], and Jackson and Green [52].”
• UNLOADING OF AN ELASTIC-PLASTIC LOADED SPHERICAL CONTACT (2005, methodology): “3 presents the elastic-plastic loading results obtained by Kogut and Etsion [13] for an elastic perfectly plastic material (Eq.”
• A Multi-Scale Model for Contact Between Rough Surfaces (2006, methodology): “A detailed description of several elasto-plastic models is given in Kogut and Etsion [5], and Jackson and Green [7].”
• A Finite Element Based Elastic-Plastic Model for the Contact of Rough Surfaces (2003, result): “of the plasticity index, Ψ. The results are shown for plasticity index values Ψ > 1.4 only, in accordance with Eq. [ 17 ] for k = 6. As can be seen at Ψ = 2 the ratio Ap/A is still very small and even for the largest load P * = 0.1 it is less than 5%. This is clearly dif-”
• Resolving the contradiction of asperities plastic to elastic mode transition in current contact models of fractal rough surfaces (2007, methodology): “This can be done by using elastic plastic single asperity contact model such as in Kogut and Etsion [ 34 ], for example, where the ratios P/Pc and a/ac are expressed as functions of ω/ωc.”
