Intersonic delamination in curved thick composite laminates under quasi-static loading
Gozluklu, Burak; Uyar, Imren; Çöker, Demirkan (2015-01-01)
Dynamic delamination in curved composite laminates is investigated experimentally and numerically. The laminate is 12-ply graphite/epoxy woven fabric L-shaped laminate subject to quasi-static loading perpendicular to one arm. Delamination initiation and propagation are observed using high speed camera and load displacement data is recorded. The quasistatic shear loading initiates delamination at the curved region which propagates faster than the shear wave speed of the material, leading to intersonic delami...
Intersonic shear crack propagation using peridynamic theory
Yolum, Ugur; Çöker, Demirkan; Guler, Mehmet A. (2021-02-01)
Dynamic crack propagation of mode-II cracks is simulated using bond-based Peridynamic Theory (PD) implemented in finite element analysis software ABAQUS. The specimen is a bonded homogeneous Homalite plate with a pre-notch that is subjected to impact shear loading simulating the experiments of Rosakis et al. (1999). The PD bonds at the bonding interface are utilized with a scalar critical stretch value that corresponds to mode-II fracture toughness of the interface. The crack initiation and propagation are ...
Intersonic shear crack growth along weak planes
Rosakis, Ares J.; Samudrala, Omprakash; Çöker, Demirkan (Informa UK Limited, 2000-01-01)
Classical dynamic fracture theories predict the Rayleigh surface wave speed (cR) to be the limiting speed of propagation for mode-I cracks in constitutively homogeneous, isotropic, linear elastic materials subjected to remote loading. For mode-II cracks, propagating along prescribed straight line paths, the same theories, while excluding the possibility of crack growth in the speed regime between cR and the shear wave speed, cs, do not exclude intersonic (cs<υ<cl) crack tip speeds. In the present study, we ...
Interlaminar tensile strength of different angle-ply CFRP composites
Yavuz, Burak Ogun; Parnas, Levend; Çöker, Demirkan (Elsevier BV; 2019-01-01)
Due to high specific strength and modulus requirements, demand for the use of polymer-based composites in structural applications has been increasing more than ever. On the other hand, their interlaminar properties are known to be relatively weak. Such structures are prone to interlaminar failures including delaminations under static or impact loads. Interlaminar tensile strength (ILTS) is one of the interlaminar properties which gives an indication of delamination onset in through the thickness loading for...
