Material issues in nuclear applications

Yalçınkaya, Tuncay
This report covers the book of abstracts of the 1st International Workshop on Physics Based Modeling of Material Properties and Experimental Observations. The workshop is organized in the context of European Commission’s Enlargement and Integration Action, by the Joint Research Centre in collaboration with the Middle East Technical University on 22nd -- 23rd October 2012 in Ankara. The abstracts of 7 keynote lectures and 19 technical presentations are included in the book. The purpose of the meeting is to discuss the current state of the art of physics based modeling of materials and associated experimental techniques. Such approaches allow a better understanding of the degradation mechanisms and the link between the microstructure and material behavior which is necessary for the extrapolation of data beyond operational experience and for the assessment of component integrity subjected to harsh environment and long term operation.


Smart structures and their applications on active vibration control: Studies in the Department of Aerospace Engineering, METU
Şahin, Melin; Yaman, Yavuz; Nalbantoglu, Volkan; Ulker, Fatma Demet; Caliskan, Tarkan (Springer Science and Business Media LLC, 2008-08-01)
This work presents the theoretical and experimental studies conducted in Aerospace Engineering Department of Middle East Technical University on smart structures with particular attention given to the structural modelling characteristics and active suppression of in-vacuo vibrations. The smart structures considered in these analyses are finite and flat aluminium cantilever beam-like (called as smart beam) and plate-like (called as smart fin) structures with surface bonded lead-zirconate-titanate patches. Fi...
Product Based Material Testing for Hyperelastic Suspension Jounce Bumper Design with FEA
Caliskan, Kemal; Konukseven, Erhan İlhan; Ünlüsoy, Yavuz Samim (2010-09-10)
The basic problem in the finite element analysis of parts made of hyperelastic materials is the identification of mathematical material model coefficients. Furthermore, selection of a suitable mathematical hyperelastic material model may not be straightforward. In this study, a systematic design methodology is presented for hyperelastic suspension jounce bumpers. The presented methodology involves a critical examination of material testing procedures, material model selection, and coefficient identification...
Multi-scale characterization of particle clustering in discontinuously reinforced composites
CETIN, Arda; Kalkanlı, Ali (Elsevier BV, 2009-06-01)
The applicability of a quantitative characterization scheme for cluster detection in particle reinforced composites is discussed. The method considers the pattern from the perspective of individual particles, so that even in a pattern that globally conforms to a random distribution, micro-scale heterogeneities can be detected. The detected clusters are visualized by kernel surfaces. Results indicate that the presented methodology is an effective discriminator of clusters and can successfully be used for qua...
Parameter optimization of chemically activated mortaars containing high volumes of pozzolan by statistical design and analysis of experiments
Aldemir, Başak; Saatçioğlu, Ömer; Department of Industrial Engineering (2006)
This thesis illustrates parameter optimization of early and late compressive strengths of chemically activated mortars containing high volumes of pozzolan by statistical design and analysis of experiments. Four dominant parameters in chemical activation of natural pozzolans are chosen for the research, which are natural pozzolan replacement, amount of pozzolan passing 45 æm sieve, activator dosage and activator type. Response surface methodology has been employed in statistical design and analysis of experi...
Cognitive aspects of conceptual modeling diagrams : an experimental study
Kılıç, Özkan; Say, Bilge; Department of Cognitive Sciences (2007)
This thesis is about diagrammatic reasoning and error-finding in conceptual modeling diagrams. Specifically, the differences of the cognitive strategies and behaviors of notation-familiar participants versus domain-familiar participants working on conceptual modeling diagrams are inspected. The domain-familiar participants are experienced in the topic being represented, but they do not have any formal training in software development representations. On the other hand, the notation-familiar participants are...
