DEM analysis of passive failure state behind a rigid retaining wall: Effect of boundary conditions
Altunbaş, Adlen; Soltanbeigi, Behzad; Çinicioǧlu, Özer (EDP Sciences, 2019)Discrete Element Modelling (DEM) is a virtual testing method that enables multiscale studies on granular materials. DEM provides a well-controlled testing environment, which enables precise systematic evaluation of the ... -
DEM modelling of retained backfill: Influence of particle shape for different stress paths and densities
Altunbaş, Adlen; Soltanbeigi, Behzad; Çinicioğlu, Özer (Techno Press, 2021)This paper investigates the relative influences of backfill particle properties and imposed stress path on the response of retained granular assemblies. The characteristics considered are particle shape, backfill density, ... -
Determination of passive failure surface geometry for cohesionless backfills
Soltanbeigi, Behzad; Altunbaş, Adlen; Gezgin, Ahmet Talha; Çinicioğlu, Özer (Budapest University of Technology and Economics, 2020)Correct determination of the passive failure surface geometry is necessary for the design of retaining structures. The conventional theories assume linear passive failure surfaces even though it is known that the actual ... -
Influence of dilatancy on shear band characteristics of granular backfills
Soltanbeigi, Behzad; Altunbaş, Adlen; Çinicioğlu, Özer (Taylor & Francis Ltd, 2021)This study investigates the evolution of strain localisation and resulting failure surfaces within cohesionless backfills. For this purpose, 1g small scale model experiments are performed simulating the lateral translation ... -
Multi-scale investigation of active failure for various modes of wall movement
Gezgin, Ahmet Talha; Soltanbeigi, Behzad; Altunbaş, Adlen; Çinicioğlu, Özer (Higher Education Press, 2021)Retained backfill response to wall movement depends on factors that range from boundary conditions to the geometrical characteristic of individual particles. Hence, mechanical understanding of the problem warrants multi-scale ... -
Multiscale analysis of active state failure behind a retaining wall
Soltanbeigi, Behzad; Altunbaş, Adlen; Çinicioǧlu, Özer (International Society for Soil Mechanics and Geotechnical Engineering, 2019)Discrete element method (DEM) simulates the interaction of particulate material by tracking the displacement and calculation of force for individual grains. Current study, initially simulates the active state failure behind ... -
Numerical analysis of failure mechanism observed in backfills supported by masonry walls
Altunbaş, Adlen; Saygılı, Özden; Keleşoğlu, Mustafa Kubilay; Lemos, Jose V. (Academia Brasileira de Ciencias, 2023)Masonry retaining walls are designed to resist lateral forces. Their stability is essentially warranted by the correct determination of the failure surface geometry. Accordingly, this study intended to investigate the ...
