Numerical and experimental investigation of frictional sliding under dynamic loading conditions is discussed. The configuration analyzed consists of two plates of Homalite (an elastic birefringent polymer material) connected along a planar interface. The plates are characterized as isotropic elastic materials and the interface is characterized by a rate- and state-dependent frictional law that also accounts for dependence on normal stress variations. The calculations are carried out within a framework where two constitutive relations are used: a volumetric constitutive relation between stress and strain and a surface constitutive relation that characterizes the frictional behavior of an interface. The propagation speeds of the sliding tip are found to be of the order of the longitudinal wave speed. Frictional sliding is found to occur in modes that involve uniform sliding behind the rupture front, an isolated slip pulse, multiple slip pulses or a combination of these modes. The dependence of the sliding mode on the initial compressive stress, the impact velocity and the friction parameters is described. Numerical results compare favorably with experimental observations in terms of intersonic sliding tip speed, crack-like and pulse-like sliding modes and the stress fields at the sliding tip.

Simulation of frictional sliding under impact shear loading
Çöker, Demirkan; Lykotrafitis, George; Rosakis, Ares J. (2004-12-01)
Results from recent and ongoing investigations of frictional sliding under dynamic loading conditions are discussed. The configuration analyzed consists of two identical elastic plates with an interface characterized by a rate- and state-dependent frictional law. The calculations are carried out within a frame-work where two constitutive relations are used: a volumetric constitutive relation between stress and strain and a surface constitutive relation that characterizes the frictional behavior of the inter...
Finite element modeling of dynamic interfacial rupture and sliding
Çöker, Demirkan; Needleman, A. (null; 2005-12-01)
Analyses of fracture and sliding under dynamic loading conditions are discussed. The calculations are carried out within a framework where two constitutive relations are used: a volumetric constitutive relation between stress and strain and a surface constitutive relation that characterizes the fracture and/or frictional behavior of an interface. Attention is confined to two dimensional plane stress or plane strain analyses. Issues that are addressed including limiting rupture and sliding speeds along inter...
Multiple Model Adaptive Estimation Algorithm for Systems with Parameter Change
Söken, Halil Ersin (2016-01-01)
This paper presents an autonomous multiple model (AMM) estimation algorithm for systems with sudden parameter changes. Estimates of a bank of Kalman filters (KFs) are merged based on a newly defined likelihood function. The function is composed of two measures, one for weighting the filters during the steady state mode and the other for weighting when there is a change in the parameters. Compared to the interacting multiple model (IMM) method, the KFs do not interact but compete on the basis of the likeliho...
DELAYED DETACHED-EDDY SIMULATION BASED PREDICTIONS OF BOUNDARY LAYER TRANSITION AND CAVITY FLOW NOISE
Yalçın, Özgür; Özyörük, Yusuf; Department of Aerospace Engineering (2021-11-1)
This dissertation investigates the boundary layer transition as well as the cavity flow noise prediction capabilities of a high-order in-house solver using various Delayed Detached-Eddy Simulation (DDES) frameworks. Before conducting the simulations, multiblock topology with a high-order overset grid technique is implemented into the solver, which makes mesh generation for complex geometries, such as the tunnel grids around blade sections, and cavity grids composed of two separate domains of the studied cas...
VERTEX PARTITIONING BASED MULTIPLE DESCRIPTION CODING OF 3D DYNAMIC MESHES
Bici, M. Oguz; Stefanoski, Nikolce; Akar, Gözde (2009-05-06)
In this paper, we propose a Multiple Description Coding (MDC) method for reliable transmission of compressed time consistent 3D dynamic meshes. It trades off reconstruction quality for error resilience to provide the best expected reconstruction of 3D mesh sequence at the decoder side. The method is based on partitioning the mesh vertices into two sets and encoding each set independently by a 3D dynamic mesh coder. The encoded independent bitstreams or so-called descriptions are transmitted independently. T...
