  • Shape optimization of bumper beam under low-velocity impact 
    Dadashzadeh, Sina. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    Bumper beam is an important part of vehicles providing protection from colli sions. Its main function is to prevent damage to the rest of the vehicle in low-speed collisions. For this reason, it should absorb the energy ...
  • Shape optimization of notched mechanical members to reduce stress concentration 
    Çilek, Ufuk. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2005., 2005.)
    Intensive competition in the market place today requires engineers to continuallysearch for better and more economic designs. Current interest especially in structural shapeoptimization is largely motivated by demands for ...
  • Shape optimization of notched parts for maximum fatigue life 
    Erkol, Volkan. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2016., 2016.)
    The objective of the thesis study is to develop a shape optimization procedure to maximize fatigue life of notched components under in-phase or out-of-phase multiaxial loading conditions. Two critical-plane fatigue assessment ...
  • Shape optimization of thin-walled tubes under high-velocity axial and transverse impact loadings 
    Tanlak, Niyazi. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    Thin-walled tubes are one of the most commonly used parts in structural ap- plications. More specifically, they are used as passive safety measures in vehicles like bumper-beams and crash-boxes. They take loads either ...
  • Strain energy based fatigue model for notched part subjected to multiaxial loading 
    Karadeniz, Cumali Özgür. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    In this study, a new fatigue assessment model is developed for high cycle fatigue of metals under multiaxial proportional loading. The proposed model uses readily available material properties and contains no parameters ...
  • Topography optimization of cylindirical shells with cutouts for maximum buckling strength 
    Gökyer, Yusuf. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    Buckling strength of shell structures under compression significantly drops if cutouts exist. In order to compensate this, these structures are reinforced with stiffeners. In this thesis, the objective is to optimize ...
