  • An investigation of the crack propagation model corpus 
    Sönmez, Fazıl Önder. (Thesis (M.S.)- Bogazici University. Institute for Graduate Studies in Sciences and Engineering, 1991., 1991.)
    Models that predict fatigue crack growth are described, classified and compared with respect to applicability and limitations. Crack opening models were found to be more reliable and better adapted to include interaction ...
  • Comparison of crack initiation criteria in functionally graded materials under mixed mode loading 
    Sürücüoğlu, Çiğdem. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    In this thesis, analytical crack initiation criteria are evaluated in detail. Finite element method is used to determine crack initiation angles for edge cracked functionally graded materials. Minimum strain energy density ...
  • Crack propagation analysis in elastomeric isolation bearings 
    Tıknaz, Emirhan. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    This thesis study focuses on the crack propagation analysis in elastomeric isolation bearings. One benchmark problem related to crack propagation analysis in a single-edge notch specimen and two problems related to interface ...
  • Design optimization of structures under fatigue loading 
    Ertaş, Ahmet Hanifi. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    Many of the engineering failures are caused by fatigue. Fatigue failure can be defined as the tendency of a material to fracture by means of progressive brittle cracking under cyclic stresses. Because mechanical components ...
  • Fatigue crack growth prediction and analysis 
    Akyürek, Turgut. (Thesis (M.S.)- Bogazici University. Institute for Graduate Studies in Science and Engineering, 1984., 1984.)
    In this thesis, A computer program predicting the fatigue life of the specimens subjected to randomized black loading is prepared. A detailed description of fatigue crack growth and predictive models are reviewed. The ...
  • Finite element analysis of plasticity-induced fatigue crack closure 
    Gökçen, Mehmet Gökhan. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    Contact elements are implemented into the elastic-plastic finite element analysis of fatigue crack closure to predict crack opening stress, by developing a code using ANSYS Parametric Design Language. Although the use of ...
  • K-dominanat region in 2-D functionally graded materials under mixed mode loading 
    Altay, Gökce. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    The extent of K-dominant region around the crack tip of a functionally graded plate under mixed mode loading is investigated. A center cracked plate is used for the study. The stress intensity factors and T-stresses are ...
  • Transformation induced crack closure and fatigue life analysis of shape memory alloys using finite elements 
    Altan, Nadir Can. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    Fatigue crack propagation behavior of shape memory alloys is investigated using finite elements. Fatigue crack growth rate is numerically determined in terms of effective stress intensity factor range and maximum stress ...
