A single edge notched geometry [SE(T)] with clamped ends is well suited for fracture toughness and fatigue crack growth testing of composites. Closed form expressions for the stress intensity factor and the compliance for an SE(T) with clamped ends were developed using finite element analysis. Using these expressions, automated crack growth tests were conducted on a monolithic Ti-1100 and a [90]8 SCS-6/Ti-24Al-l 1Nb composite. The crack growth behavior, characterized in terms of the crack growth rate versus the applied stress intensity factor range, correlated well with available data obtained using the compact tension geometry. The results of this investigation indicate that the SE(T) geometry with clamped ends can be successfully used for fracture and fatigue crack growth testing of monolithic and composite specimens.

CRACK-GROWTH KINETICS OF 7050-T73651 ALUMINUM-ALLOY UNDER CONSTANT LOAD AT 150-DEGREES-C
SARIOGLU, F; ABACHI, P; DORUK, M (Springer Science and Business Media LLC, 1993-03-15)
Crack growth tests at 150-degrees-C under constant load conditions were performed on compact tension specimens of 7050-T73651 aluminium alloy. The d.c. potential drop method was employed to monitor crack lengths throughout the tests. Fracture mechanics parameters such as the stress intensity factor (K) and energy-rate line integral (C*) were used to establish correlation with the crack propagation rates. As a result of experiments it was found that crack growth rates (da/dt) versus K, over discrete ranges o...
Impact essential work of fracture toughness of ABS/polyamide-6 blends compatibilized with olefin based copolymers
Ozkoc, Guralp; Bayram, Göknur; Bayramli, Erdal (Springer Science and Business Media LLC, 2008-04-01)
The impact fracture toughness of acrylonitrile-styrene-butadiene/polyamide-6 (ABS/PA6) blends compatibilized with 5% by weight carbon monoxide modified ethylene-n butyl acrylate-maleic anhydride (EnBACO-MAH) or ethylene-methyl acrylate-glycidyl methacrylate (EMA-GMA) copolymers were examined as a function of blend ratio by standard Charpy tests, Essential Work of Fracture (EWF) Methodology and fracture surface morphologies. The samples were first processed in twin-screw extruder and they were subsequently i...
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 category of experiments deals with characterizing nonlinear vibrations of beams containing breathing cracks. To produce cracked beam specimens, fatigue cracks can be grown ahead of sharp notches under controlled loading. ASTM E399 and ASTM E1820 standards provide guidance on such procedures...
Effect of microstructural modification on damage tolerance of 34CrMo4 shaft steel
Ozcan, Burak; Gurer, Goksu; Gür, Cemil Hakan (Wiley, 2020-06-01)
Overall damage tolerances of the heat-treated 34CrMo4 steels having ferritic-pearlitic, bainitic, and tempered-martensitic microstructures were evaluated based on their threshold stress intensity factor prior to small crack propagation, fatigue strength, and fracture toughness under static loading. Kitagawa-Takahashi diagrams were constructed to determine the limiting size of small crack propagation. The micromechanical effects of carbide morphology and phase distribution on quasi-static and dynamic mechani...
Edge cracks in a transversely isotropic hollow cylinder
Kadıoğlu, Fevzi Suat (Elsevier BV, 2005-09-01)
The analytical solution for the linear elastic, axisymmetric problem of inner and outer edge cracks in a transversely isotropic infinitely long hollow cylinder is considered. The z = 0 plane on which the crack lies is a plane of symmetry. The loading is uniform crack surface pressure. The mixed boundary value problem is reduced to a singular integral equation where the unknown is the derivative of the crack surface displacement. An asymptotic analysis is done to derive the generalized Cauchy kernel associat...
