A single edge cracked geometry with clamped ends is well suited for fracture toughness and fatigue crack growth testing of composites and thin materials. Analysis of fiber bridging phenomenon in the composites and determination of stress intensity factors due to non-uniform stress distributions such as residual and thermal stresses generally require the use of a weight function. This paper describes the development and verification of a weight function for the single edge cracked geometry with clamped ends. Finite element analyses were conducted to determine the stress intensity factors (K) and crack opening displacements (COD) due to different types of stress distributions. The weight function was developed using the K and COD solution for a constant stress distribution. K and COD predicted using this weight function correlated well with the finite element results for non-uniform crack surface stress distributions.

Stress intensity factor and compliance solutions for a single edge notched specimen with clamped ends
Blatt, Drew; John, Reji; Çöker, Demirkan (Elsevier BV, 1994-01-01)
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...
Hyperbolic heat conduction based weight function method for thermal fracture of functionally graded hollow cylinders
Eshraghi, Iman; Soltani, Nasser; Dağ, Serkan (2018-08-01)
This article introduces a weight function method for fracture analysis of a circumferentially cracked functionally graded hollow cylinder subjected to thermal loads. The non-Fourier hyperbolic heat conduction model is used to determine the transient temperature distribution in the functionally graded cylinder. Solutions for transient temperature and stress distributions in the uncracked cylinder are derived by converting the governing differential equations into Fredholm integral equations in the Laplace do...
Mode I fracture toughness determination with straight notched disk bending method
Tutluoğlu, Levend (2011-12-01)
A new method called the straight notched disk bending method is developed for mode I fracture toughness determination using rock cores. Disk specimens of andesite and marble having a single straight edge notch were subjected to three-point bending loads. Dimensionless stress intensity factor estimations and fracture toughness tests were conducted for different notch lengths, span lengths, thicknesses and diameters of the cylindrical rock specimens. Stress intensity factors were computed by three-dimensional...
Weight function method for transient thermomechanical fracture analysis of a functionally graded hollow cylinder possessing a circumferential crack
Eshraghi, Iman; Soltani, Nasser; Dağ, Serkan (Informa UK Limited, 2016-01-01)
This article introduces a weight function method for fracture analysis of a circumferentially cracked functionally graded hollow cylinder subjected to transient thermomechanical loading. Analytical solutions for transient temperature and stress distributions in the uncracked cylinder are derived by applying finite Hankel transformation. These solutions are utilized to determine stress acting on the faces of the circumferential crack in the local perturbation problem. Thermomechanical material properties are...
Investigation of proper specimen geometry for mode I fracture toughness testing with flattened Brazilian disc method
KELES, Cigdem; Tutluoğlu, Levend (2011-05-01)
Investigation of geometrical parameters for flattened Brazilian disc method is important, since this is a simple and attractive method for mode I fracture toughness testing on rock cores. Evaluating numerical modeling results, a parametric equation in terms of principal stresses at the center of the disc and the loading angle of the flattened end was developed. An equation was proposed for maximum stress intensity factors at critical crack lengths around stable to unstable crack propagation. Comparing fract...
