Analysis of crack initiation and propagation in solid rocket motor nozzle throats
Nigar, Barış; Özerinç, Sezer; Department of Mechanical Engineering (2019)
Graphite is a widely used material in high temperature structural applications due to its high melting point and its mechanical strength and integrity at elevated temperatures. However, rocket nozzles made of graphite are subjected to very high temperatures and pressures that cause cracking and eventual failure. This thesis investigates the reasons of failure and explores design alternatives to overcome this problem. The experimental part of the thesis includes compression tests, tensile tests and fracture ...
Analysis of the effects of vertical pre-release cracks on prestressed concrete bridge girders
Baran, Eray; French, Catherine; Wyffels, Tina (Precast/Prestressed Concrete Institute, 2004-11-01)
Vertical cracks, termed "pre-release cracks," beginning at the top flange and propagating downward into the section depth have been observed to develop during the production of long-span prestressed concrete bridge girders. The cracking which is attributed to the restrained shrinkage the concrete and thermal effects during the curing period prior to release of the prestressing strands, tends to be more critical for long-span girders with deep sections and large amounts of prestressing strands. Studies were ...
Analysis of mechanical behavior of high performance cement based composite slabs under impact loading
Satıoğlu, Azize Ceren; Gülkan, Polat; Department of Civil Engineering (2009)
Studies on the behavior of steel fiber reinforced concrete (SFRC) and slurry infiltrated fibrous concrete (SIFCON) to impact loading have started in recent years. Using these relatively new materials, higher values of tensile and compressive strength can be obtained with greater fracture toughness and energy absorption capacity, and therefore they carry a considerable importance in the design of protective structures. In this thesis, computational analyses concerning impact loading effect on concrete, steel...
Analysis of blast loading effect on regular steel building structures
Tahmilci, Fatih; Caner, Alp; Department of Civil Engineering (2007)
Concern about effect of explosives effect on engineering structures evolved after the damage of Second World War. Beginning from 90’s with the event of bombing Alfred P. Murrah Federal building located in Oklahoma City this concern deepened and with the attack to World Trade Center twin towers on September 11, 2001 it is peaked. Recent design codes mainly focus on earthquake resistant design and strengthening of the structures. These code design methodologies may sometimes satisfy current blast resistant de...
Analysis of slot coupled microstrip patch antennas
Ballıkaya, Elif; Aydın Çivi, Hatice Özlem; Department of Electrical and Electronics Engineering (2007)
Method of Moments (MoM)/Green’s function formulation is developed for the analysis of electromagnetic radiation from planar rectangular microstrip antennas with different feeding techniques. Investigated structures are microstrip line fed patch antenna, proximity coupled patch antenna and slot coupled patch antenna. For all these structures equivalent problems are defined. Then, integral equations where currents are the unknowns are obtained from boundary conditions and by using spectral domain representati...
