A simple three-dimensional soil-structure interaction (SSI) model is proposed. First, a model is developed for a layered soil medium. In that model, the layered soil medium is divided into thin layers and each thin layer is represented by a parametric model. The parameters of this model are determined, in terms of the thickness and elastic properties of the sublayer, by matching, in frequency-wave number space, the actual dynamic stiffness matrices of the sublayer when the sublayer is thin and subjected to plane strain and out-of-plane deformations with those predicted by the parametric model developed in this study. Then, by adding the structure to soil model a three-dimensional finite element model is established for the soil-structure system. For the floors and footings of the structure, rigid diaphragm model is employed. Based on the proposed model, a general computer software is developed. Though the model accommodates both the static and dynamic interaction effects, the program is developed presently for static case only and will be extended to dynamic case in a future study. To assess the proposed SSI model, the model is applied to four examples, which are chosen to be static so that they can be analyzed by the developed program. The results are compared with those obtained by other methods. It is found that the proposed model can be used reliably in SSI analysis, and accommodates not only the interaction between soil and structure; but, also the interaction between footings.

An orthotropic viscoelastic material model for passive myocardium: theory and algorithmic treatment CANSIZ, F. Baris Can; Dal, Hüsnü; KALISKE, Michael (Informa UK Limited, 2015-08-18) This contribution presents a novel constitutive model in order to simulate an orthotropic rate-dependent behaviour of the passive myocardium at finite strains. The motivation for the consideration of orthotropic viscous effects in a constitutive level lies in the disagreement between theoretical predictions and experimentally observed results. In view of experimental observations, the material is deemed as nearly incompressible, hyperelastic, orthotropic and viscous. The viscoelastic response is formulated ...
A modified applied element model for the simulation of plain concrete behaviour Soysal, Berat Feyza; Arıcı, Yalın; Tuncay, Kağan (2022-08-01) A modified applied element model to simulate the behaviour of plain concrete continuum structures including discrete cracking is proposed in this study. In the classical applied element model, Poisson effects are fully ignored. To remediate this issue, diagonal elements are introduced to include the Poisson effect, and the constitutive parameters are rigorously determined using the Cauchy-Born rule and the hyper-elastic theory. The formulation is validated for linear elastic problems and the consistency and...
A generative model for multi class object recognition and detection Ulusoy, İlkay (2006-01-01) In this study, a generative type probabilistic model is proposed for object recognition. This model is trained by weakly labelled images and performs classification and detection at the same time. When test on highly challenging data sets, the model performs good for both tasks (classification and detection).
A modulus gradient model for an axially loaded inhomogeneous elastic rod Gulasuk, Hasan; Göktepe, Serdar; Gürses, Ercan (2018-08-01) A new gradient elasticity formulation is proposed for a one-dimensional linear elastic inhomogeneous rod. In the new formulation, similar to the differential relation between the local strain and the gradient enhanced strain in the classical models of gradient elasticity, a differential relation is proposed for the Young's modulus. Analytical and finite element solutions of the proposed formulation are derived. Results of the proposed model are compared with a classical model of gradient elasticity for a mo...
A projection based variational multiscale method for a fluid–fluid interaction problem Ağgül, Mustafa ; Eroğlu, Fatma Güler ; Kaya Merdan, Songül; Labovsky, Alexer E. (Elsevier BV, 2020-06-15) The proposed method aims to approximate a solution of a fluid–fluid interaction problem in case of low viscosities. The nonlinear interface condition on the joint boundary allows for this problem to be viewed as a simplified version of the atmosphere–ocean coupling. Thus, the proposed method should be viewed as potentially applicable to air–sea coupled flows in turbulent regime. The method consists of two key ingredients. The geometric averaging approach is used for efficient and stable decoupling of the pr...
