Deformation characteristics of medium-dense sand-clay mixtures under a principal stress rotation
Fedakar, Halil Ibrahim; Cetin, Bora; Rutherford, Cassandra J. (ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021)A moving wheel load induces a principal stress rotation (PSR) in pavement foundation geomaterials including subgrade/subbase soils. Simulating such a stress condition is not possible with stress path tests conducted with ... -
Developing New Empirical Formulae for the Resilient Modulus of Fine-Grained Subgrade Soils Using a Large Long-Term Pavement Performance Dataset and Artificial Neural Network Approach
Fedakar, Halil Ibrahim (SAGE Publications Ltd, 2022)Artificial neural network (ANN) has been successfully used for developing prediction models for resilient modulus (Mr). However, no reliable Mr formula derived from these models has been proposed in previous studies, ... -
Effect of principal stress rotation on deformation behavior of dense sand-clay mixtures
Fedakar, Halil Ibrahim; Rutherford, Cassandra J.; Cetin, Bora (TAYLOR & FRANCIS LTD2-4 PARK SQUARE, MILTON PARK, ABINGDON OR14 4RN, OXON, ENGLAND, 2021)This paper investigated the deformation behaviour of K-consolidated sand-clay mixtures through cyclic triaxial (CT) and hollow cylinder (CHC) tests. The sand-clay mixtures contained 0%, 5%, 10% and 20% clay by weight and ... -
Modeling of suspended sediment concentration carried in natural streams using fuzzy genetic approach
Kisi, Ozgur; Fedakar, Halil Ibrahim (SPRINGER LINK, 2014)This chapter proposes fuzzy genetic approach so as to predict suspended sediment concentration (SSC) carried in natural rivers for a given stream cross section. Fuzzy genetic models are improved by combining two methods, ... -
Poliüretan ile Güçlendirilmiş Balastın Hareket Eden Tekerlek Yükü Altındaki Deformasyon Davranışının Nümerik Olarak İncelenmesi
Fedakar, Halil Ibrahim (Çukurova Üniversitesi, 2022)Hareket eden tekerlek yükünden dolayı balastlı demiryolu hatlarında meydana gelen düşey deformasyonlar özellikle yüksek tren hızlarında ve zayıf taban zemini koşullarında hat düzensizliklerine sebep olmaktadır. Bu durum ...
