Fracture analysis of welded connections
Yetgin, Ali; Kadıoğlu, Fevzi Suat; Department of Mechanical Engineering (2013)
The main objective of this thesis is to evaluate structural integrity of a multi barrel launcher system on fracture mechanics basis by using finite element method. A global finite element model that includes necessary kinematic and elastic connections is built. Dynamic firing forces are applied on global finite element model and general structural response is obtained. Sub modeling method is used in order to perform crack analysis. Since size of global model is too large to include solid crack elements whic...
Fracture analysis of spun-cast concrete poles using the phase-field method
Azim Azary, Ali; Göktepe, Serdar; Department of Civil Engineering (2017)
Shrinkage is an important type of deformation in hardening concrete, which happens mainly in the cement paste and may cause significant damage if restrained. Spun-cast concrete poles are among structural members that are prone to this type of damage if not fabricated properly. They are used extensively in structures such as columns, piles, and utility poles to name a few. In this thesis, we study the differential shrinkage-induced cracking in spun-cast members computationally using the Phase Field Method wi...

Fatigue crack growth behaviors of rail R260 and rail R350 HT in head, web and foot region of the rail have been investigated. Crack propagation at these three regions were compared. Furthermore, Fracture toughness (KIC) values in the three region of the rail R260 and R350 HT were calculated. Compact shear specimens were machined from the web of the rail in the longitudinal direction to conduct KIIC fracture toughness of the rail R260. A special loading frame manufactured for KIIC testing. Fractographic anal...
