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 interface. The simulations discussed predict a variety of sliding modes including a crack-like mode and several pulse-like modes as well as circumstances where the sliding tip speed can exceed the longitudinal wave speed.

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...
Performance of a moment resisting beam-column connection for precast concrete construction Baran, Eray; BARAN, MEHMET; Kurtoglu, Metin; Torra-Bilal, Ines (2021-11-01) Seismic performance of a specific type of moment resisting precast concrete beam-column connection was investigated through reversed cyclic load tests. Structural steel components were incorporated with precast concrete beam and column elements in the experiments to provide a ductile moment resisting connection. Additionally, nonlinear finite element analysis (FEA) of typical monolithic and precast connections was performed to investigate the performance and failure modes of these connections. Concrete Dama...
Crack-like and pulse-like dynamic frictional sliding Çöker, Demirkan; Needleman, A.; Rosakis, A.j. (2005-12-01) 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...
Comparison of the Overlapping Lattice and the Finite Element Approaches for the Prediction of the Collapse State of Concrete Gravity Dams Soysal Albostan, Berat Feyza; Arıcı, Yalın; Binici, Barış; Tuncay, Kağan (2017-10-13) 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. In this context, the purpose of the study is to investigate the prediction capability of numerical tools in determining the collapse state of concrete gravity dams. The first tool used to this end is the classical finite element method with the smeared crac...
Analysis of ratcheting by using different yield criteria and kinematic hardening models for uniaxial and biaxial loading İşler, Mert; Darendeliler, Haluk; Department of Mechanical Engineering (2018) Ratcheting, the accumulation of plastic strain under cyclic loading, will be investigated for uniaxial and biaxial loading in this study. The simulations of ratcheting will be carried on for different yield criteria and kinematic hardening rules. The corresponding stress-strain relations will be developed and used in the numerical analysis by implementing subroutines to a commercial finite element software. The numerical results will be compared with the experimental ones to evaluate the applicability of th...
