Probabilistic friction model for aluminium–steel Asymmetric Friction Connections (AFC)

Multiple physical variables potentially affect the friction coefficient of Asymmetric Friction Connections (AFC). This paper discusses cyclic response a class AFC subjected to repeated load protocols. Two phenomena are observed. First, coefficient, initially higher due wear and moment-axial force-shear force interaction, stabilizes after multiple cycles. Second, test repetitions on same specimen show that at beginning loading protocol is than observed end antecedent protocol. The experimental data prove dissipated energy during current test, temperature, specimen’s history coefficient. presents two probabilistic models calibrated using Bayesian approach. first engineering-oriented model dependent hysteretic energy. second includes measured temperature as regressor estimate its possible role in response. proposed can be used predict with satisfactory accuracy Coulomb-like hysteresis AFCs. • Repeated tests Temperature effects for AFC.
