Burridge and Knopoff proposed a mass-spring model to explore interface dynamics along a fault during an earthquake. The Burridge and Knopoff (BK) model is composed of a series of blocks of equal mass connected to each other by springs of same stiffness. The blocks also are attached to a rigid driver via another set of springs that pulls them at a constant velocity against a rigid substrate. They studied dynamics of interface for an especial case with ten blocks and a specific set of fault properties. In our study effects of Coulomb and rate-state dependent friction laws on the dynamics of a single block BK model is investigated. The model dynamics is formulated as a system of coupled nonlinear ordinary differential equations in state-space form which lends itself to numerical integration methods, e.g. Runge-Kutta procedure for solution. The results show that the rate and state dependent friction law has the potential of triggering dynamic patterns that are different from those under Coulomb law.

Frictional sliding modes along an interface between identical elastic plates subject to shear impact loading Çöker, Demirkan; Needleman, A.; Rosakis, A.J. (2005-04-01) Frictional sliding along an interface between two identical isotropic elastic plates under impact shear loading is investigated experimentally and numerically. The plates are held together by a compressive stress and one plate is subject to edge impact near the interface. The experiments exhibit both a crack-like and a pulse-like mode of sliding. Plane stress finite element calculations modeling the experimental configuration are carried out, with the interface characterized by a rate and state dependent fr...
Parametric study of interface dynamics for sliding contact of elastic body on a rigid surface using Burridge-Knoppoff model Amireghbali, Aydin; Çöker, Demirkan (null; 2017-09-10) To explore the role of friction along a fault on the earthquake mechanism a simple model proposed by Burridge and Knopoff in 1967. The model is composed of a series of blocks of equal mass connected to each other by springs of same stiffness. The blocks also are attached to a rigid driver via another set of springs that pulls them at a constant velocity against a rigid substrate. In their work a special friction law which takes seismic radiation and viscosity effects into account is considered. They studied...
Friction identification and compensation of its effects in stabilized platforms Sincar, Eyyüp; Balkan, Raif Tuna; Platin, Bülent Emre; Department of Mechanical Engineering (2013) A frequent problem encountered in the stabilization of a dynamic system supported by a moving base is the disturbance rejection associated with moving components. Due to relative motion of adjacent components, the friction induces a destabilizing force from base motion to the stabilized object, which degrades the motion accuracy. Therefore, the compensation of frictional effects is necessary in order to obtain a highly precise stabilization performance, especially, when the stabilized system undergoes low-v...
Physics Based Earthquake Triggering and Fault Interactions Sopacı, Eyüp; Özacar, Atilla Arda; Department of Geodetic and Geographical Information Technologies (2023-01-06) The knowledge of earthquake triggering and stress coupling mechanisms suffer data reliability in time and space. Here, the problems are analyzed with physics-based models to fill this gap using the most established empirical friction laws. First, the effects of certain state laws on earthquake triggering are analyzed in both numerical and analytical methods. The results reveal that mechanical state changes depend highly on the healing and weakening terms, and under certain conditions, the dynamic triggering...
Overlapping Lattice Simulation of Concrete Gravity Dam Collapse Simulations SOYSAL, BERAT FEYZA; Aydın, Beyazıt Bestami; Tuncay, Kağan; Arıcı, Yalın; Binici, Barış (2017-09-01) Estimating the collapse limit state of concrete gravity dams within the framework of performance based design is challenging due to the uncertainty in modelling the response of these systems and the strong dependence of the behavior on the ground motion. The purpose of the study is to investigate the seismic expected damage levels by using the overlapping lattice modeling (OLM) approach with incremental dynamic analysis (IDA) for two representative dam monoliths. OLM employs pin connected bar elements exten...
