In this work, a design methodology for advanced composite structures with holes is presented. A three dimensional finite element model (FEM) is constructed to simulate such a structural application similar to weight-pockets in helicopter blades. Material properties are obtained by a material characterization study. The progressive failure method with FEM is used for the material degradation. In order to induce delamination in simulation, cohesive layers are implemented between composite layers. Results are compared for sudden and progressive failure. Experiments are also conducted and the optimum computational approach to predict failure in such structures is discussed.

Failure analysis of tapered composite structures under tensile loading
Çelik, Ozan; Parnas, Kemal Levend; Department of Mechanical Engineering (2016)
A three dimensional finite element modeling approach is used to evaluate the effects of preliminary design variables on the performance of tapered composite laminates under tensile loading. Hashin failure criteria combined with a progressive failure algorithm is used for in-plane failure mechanisms and cohesive zone method is used for out-of-plane failures. The modeling approach is validated by a comparison with experimental results from literature. The validated model is used to examine various design vari...
Technological characteristics of abrick masonry structure and their relationship with the structural behaviour /
Aktaş, Yasemin Didem; Türer, Ahmet; Department of Archaeometry (2006)
The aim of this study is to investigate the physical and mechanical properties of construction materials in relation with the structural behaviour of a historic structure. Within this framework, the brick masonry superstructure of Tahir ile Zuhre Mescidi, a XIIIth century Seljuk monument in Konya was selected as case study. The study started with the determination of the basic physical (bulk density, effective porosity, water absorption capacity), mechanical (modulus of elasticity, uniaxial compressive stre...
Comparative study of finite element analysis and geometrically exact beam analysis of a composite helicopter blade
Ataç, Meryem Nisa; Kayran, Altan; Department of Aerospace Engineering (2018)
In this master thesis, comparative study of the finite element analysis and geometrically exact beam analysis of a composite helicopter blade is performed. The objective of this study is to investigate the applicability of the geometrically exact beam analysis of the composite helicopter blade in predicting the structural response of the composite blade. To evaluate the structural response determined by the geometrically exact beam analysis of the composite blade, detailed finite element model of the blade ...
Failure analysis of thick composites
Erdem, Melek Esra; Parnas, Kemal Levend; Department of Mechanical Engineering (2013)
A three-dimensional finite element model is constructed to predict the failure of a hybrid and thick laminate containing bolted joints. The results of the simulation are compared with test results. The simulation comprises two main challenging steps. Firstly, for a realistic model, a 3D model is established with geometric nonlinearities and contact is takeninto account. The laminated composite model is constructed by 3D layered elements. The effect of different number of elements through the thickness is in...
Experimental and analytical investigation of the size effect on the strength of open hole composite laminates
Gezer, Ali; Çöker, Demirkan; Department of Aerospace Engineering (2021-12-10)
In this thesis, we investigate the effect of size on the strength of open hole composite laminates using experimental and analytical approaches. The size effect consists of the effect of thickness and hole size while keeping width to diameter ratio constant. In the experimental part of this work, tensile tests are conducted on CFRP open hole specimens. In-situ images of the top and side surfaces of the test specimens are captured throughout the experiments and load displacement curves are acquired from the ...
