How to distinguish between stick-slip and pure slip oscillations

TL;DR

This paper investigates how to differentiate between stick-slip and pure slip oscillations using numerical simulations of a Burridge-Knopoff model, proposing amplitude behavior as a distinguishing criterion.

Contribution

The study introduces a new criterion based on amplitude increase with driving velocity to distinguish oscillation types in the Burridge-Knopoff model.

Findings

Amplitude increases with driving velocity in simulations.

Amplitude behavior can serve as a criterion for distinguishing oscillation types.

Numerical evidence supports the proposed criterion.

Abstract

Numerical simulations are performed for the stick-slip motion in the Burridge-Knopoff model of one block. Calculated amplitude increases with the driving velocity. We argue that this effect can be a criterion to distinguish between the stick-slip and pure slip oscillations.
