Simulation of crack closure effect on cracked beam vibrations Günhan, Dağhan; Acar, Bülent; Kadıoğlu, Fevzi Suat (2024-05-02) Vibrations of beams containing cracks are usually investigated by using open or breathing crack models. Neither one of these approaches considers the plasticity induced crack closure (PICC) phenomena which occurs in fatigu...
Bond-based peridynamic fatigue analysis of ductile materials with Neuber’s plasticity correction Altay, Ugur; Dorduncu, Mehmet; Kadıoğlu, Fevzi Suat; Madenci, Erdogan (2024-01-01) This study introduces an approach for performing bond-based (BB) peridynamic (PD) fatigue analysis of ductile materials. Existing BB PD fatigue models do not account for the effect of plastic deformation. The current appro...
Dual Horizon Peridynamic Approach for Studying the Effect of Porous Media on the Dynamic Crack Growth in Brittle Materials Altay, Ugur; DÖRDÜNCÜ, MEHMET; Kadıoğlu, Fevzi Suat (2024-01-01) This study aims to investigate the effect of the stop-hole configurations on dynamic cracks using the dual-horizon peridynamic approach (DHPD). The traditional PD formulations require uniform discretization for the solutio...
An improved peridynamic approach for fatigue analysis of two dimensional functionally graded materials Altay, Ugur; DÖRDÜNCÜ, MEHMET; Kadıoğlu, Fevzi Suat (2023-12-01) This study investigates the fatigue behavior of functionally graded materials (FGMs) within an enhanced peridynamic (PD) framework that eliminates the need for surface and volume correction factors. FGMs offer mechanical a...
Stress redistribution around fiber breaks in unidirectional steel fiber composites considering the nonlinear material behavior SABUNCUOĞLU, BARIŞ; Mutlu, Çağlar; Kadıoğlu, Fevzi Suat; Swolfs, Yentl (Elsevier BV, 2020-05-01) The use of steel fibers as reinforcement in polymer composites is recently increasing thanks to their ductility, high stiffness and wide range of diameters. Unlike carbon and glass fibers, steel fibers often end up with a ...
Fiber/matrix interface stress analysis of flax-fiber composites under transverse loading considering material nonlinearity SABUNCUOĞLU, BARIŞ; Cakmakci, Onur; Kadıoğlu, Fevzi Suat (SAGE Publications, 2020-05-01) Distribution of stresses in fiber/matrix interface in UD flax fiber reinforced composites is investigated under transverse loading and compared with conventional synthetic fibers. Micro-scale finite element models with rep...
Fatigue Precracking Time Estimates for Three-Point Bending Specimens Ghasabi, A. Alipour; Motameni, A; Kadıoğlu, Fevzi Suat (Springer Science and Business Media LLC, 2019-10-01) Specimens containing sharp cracks are needed in certain types of mechanical tests, first and foremost for fracture toughness measurement of materials. Their use, however, is not just limited to this type of test. Another c...
Critical crack size investigation method for a land launcher Yetgin, A.; Acar, B.; Kadıoğlu, Fevzi Suat (2018-01-01) Structural integrity evaluation of military systems is vital in such applications as rocket launchers. In safe life design, for a certain operational life the system is ensured to function well and no failure would occur e...
Non-linear dynamic analysis for the lateral vibration of beams with breathing crack under harmonic excitation using finite element method Özkan, Berkay; Ciğeroğlu, Ender; Özgen, Gökhan Osman; Kadıoğlu, Fevzi Suat (null; 2017-06-09) Non-linear dynamic characteristics of beam with breathing crack were investigated using finite element method. Capability of detecting cracks is demonstrated by observing the sub and super harmonics on the forced vibration...
Vibration Analysis of a Cracked Beam on an Elastic Foundation Batihan, Ali Cagri; Kadıoğlu, Fevzi Suat (2016-06-01) The transverse vibrations of cracked beams with rectangular cross sections resting on Pasternak and generalized elastic foundations are considered. Both the Euler-Bernoulli (EB) and Timoshenko beam (TB) theories are used. ...
