BOWED STRING SIMULATION USING AN ELASTO-PLASTIC FRICTION MODEL
Stefania Serafin, Federico Avanzini, Davide Rocchesso · 2003
This paper proposes a digital waveguide model of a bowed string in which the interaction between the bow and the string is mod-eled using an elasto-plastic friction model. The interaction model is presented, and its advantages with respect to usual static mod-els are discussed. Details about the numerical implementation are addressed. Numerical simulations show that a hysteresis loop in the friction versus velocity plane is created, which is qualitatively compatible with experiments on real instruments and with the be-havior of a recently proposed thermodynamical friction model ap-plied to bowed string simulations. 1.
