In this thesis study, launch tube covers are investigated and a frangible cover is designed by using composite materials. Requirements which are derived from system level requirements are taken into consideration during the design phase. Suitable composite manufacturing method and materials are selected after literature survey. Load levels are determined by using experimental and analytical approaches. Material constants and limits are obtained from literature and coupon tests. Design parameters of the cover are chosen and determined by using finite element analysis. After conducting sizing of the cover by using finite element analysis, detailed design is completed. After that, a mold is produced in order to be used for resin transfer molding and cover prototypes are manufactured. A burst test set-up is designed and covers are tested in order to obtain inner and outer burst pressures. Experimental results are compatible with analytical results. Then the cover is used in firing test and desired results are observed.

Numerical investigation of stiffened composite panel into buckling and post buckling under combined loading
Akay, Erkan; Yaman, Yavuz; Department of Aerospace Engineering (2015)
This thesis presents the investigation of buckling and post buckling behaviour of stiffened thin walled laminated composite aerospace structures subjected to combined in-plane axial and shear loadings. Due to the fact that the state of stress developing especially in the post-buckling stage is quite complicated under the combined loading, the necessary computational model is usually based on Finite Element Modelling (FEM). In this study, after verifying the FEM methodology and completing the sensitivity stu...
Design of a tuned vibration absorber for a slender hollow cylindrical structure
Aksoy, Tuğrul; Özgen, Gökhan Osman; Acar, Bülent (Informa UK Limited, 2020-09-01)
In this paper, details of the design work for a tuned vibration absorber to be used on a hollow cylindrical structure is presented. The vibration problem is of resonant type and the tuned vibration absorber is designed to suppress the displacement vibration response of the free end of the slender hollow structure dominated by the contribution of its lowest transverse vibration modes. The structure is modeled using a commercial finite element software. Finite element model of the structure is verified using ...
Use of split-disk tests for the process parameters of filament wound epoxy composite tubes
Kaynak, Cevdet; PARNAS, LEVENT; ŞENEL, FİKRET (2005-08-01)
The aim of this study was to investigate processing parameters of continuous fiber reinforced epoxy composite tubes produced by the filament winding technique. For this purpose, split-disk tests (according to ASTM D-2290 standard) were performed for the specimens produced with two different epoxy resin systems, five different fiber materials and five different winding angles. By determining the hoop tensile strength and modulus of these specimens, the effects of three filament-winding processing parameters;...
Experimental and numerical failure analysis of advanced composite structures with holes
Atar, Mehmet Bilal; Parnas, Kemal Levend; Department of Mechanical Engineering (2016)
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 ...
Design of a high temperature erosion apparatus for testing of boiler tubes
Ergün, Hüseyin; Aydınol, Mehmet Kadri; Öztürk, Tayfur; Doruk, Mustafa (2013-07-25)
An apparatus was designed that enables the testing of boiler tubes against erosion. The apparatus makes use of a tube sample and simulates conditions similar to those prevailing in boilers in lignite-based power plants. The apparatus is composed of 3 components: a furnace for heating the sample, a loading system that allows the application of tensile stresses while allowing its rotation, and an erosion unit that delivers abrasive particles to the surface of the sample. The unit, as designed, would allow tes...
