Description of sand–metal friction behavior based on subloading-friction model

Abstract A subloading-friction model is formulated to describe the smooth transient variation from static friction kinetic friction, recovery after sliding velocity decreases, and accumulation of displacement under cyclic loading contact stress. In past relevant studies, however, formulation used for simulations limited hypoelastic-based plasticity framework, validation test data metal-to-metal friction. this study, based on a hyperelastic-based framework adopted. fields civil, geotechnical, agricultural engineering, terramechanics, interaction between soils metals critical, as reflected in construction machinery, foundation piles, retaining walls. The validity describing various sands verified by experimental monotonic loadings.
