Asperity micro-contact models as applied to the deformation of rough line contact (2012, background): “[8] who provided an elastic-elasto/plastic-fully plastic model that bridges the elastic and plastic behavior of the asperity using an analytical function.”
A Review of Elastic–Plastic Contact Mechanics (2017, methodology): “Many researchers [5,41,52,61–73] have studied the average pressure in the fully plastic regime to match theoretical predictions against the experimental indentation results of Brinell [74] and Meyer [75].”
A statistical model of elasto-plastic asperity contact between rough surfaces (2006, positive): “A sampling of the experimental values reported by Nuri and Halling [8] and implemented in numerical simulations by Chang et al. [9] and Zhao et al. [10], are presented in Table 1, along with the resulting values of s/R and a/R, using D ¼ 1 and o* ¼ 1.”
Film Thickness and Asperity Load Formulas for Line-Contact Elastohydrodynamic Lubrication With Provision for Surface Roughness (2012, background): “[21] developed a comprehensive asperity contact model which considered the elastic, plastic and elasto-plastic deformation of the asperities.”
Predicting the coefficient of restitution of impacting elastic-perfectly plastic spheres (2010, methodology): “This normalization scheme has been employed in many previous works [8, 17, 18, 27, 32].”
A numerical model for elastoplastic rough contact (2001, methodology): “Simple plasticity ideas have recently been incorporated into this approach [Zhao, Maietta, and Chang (2000)].”
A Multi-Scale Model for Contact Between Rough Surfaces (2006, background): “While these are not the only modeling options [3,5,6], their use will suffice for investigating the multi-scale formulation.”
