Numerical Determination of Crack Opening and Closure Stress Intensity Factors
present work shows the numerical determination of fatigue crack opening and closure stress intensity factors of a C(T) specimen under variable amplitude loading using a finite element method. A half compact tension C(T) specimen, assuming plane stress constraint was used by finite element method covering the effects in two-dimensional (2D) small scale yielding models of fatigue crack growth und...
متن کامل: 3D translational motion estimation from 2D displacements
Recovering 3-D motion parameters from 2-D displacements is a di cult task, given the in uence of noise contained in these data, which correspond at best to a crude approximation of the real motion eld. The need for stability of the system of equations to solve is therefore essential. In this paper, we present a novel method based on an unbiased estimator that aims at enhancing this stability an...
متن کاملEstimation of Stress Intensity Factors from Near Crack Tip Field
All current experimental methods for determination of stress intensity factors are based on the assumption that the state of stress near the crack tip is plane stress. Therefore, these methods rely on strain and displacement measurements made outside the near crack tip region affected by the three-dimensional effects or by process zone. In this paper, we develop and validate an experimental pro...

متن کاملDetermining the Toughness of Ceramics from Vickers Indentations Using the Crack-Opening Displacements: An Experimental Study
Recently, a method for evaluating the fracture toughness of ceramics has been proposed by Fett based on the computed crack-opening displacements of cracks emanating from Vickers hardness indentations. To verify this method, experiments have been conducted to determine the toughness of a commercial silicon carbide ceramic, Hexoloy SA, by measuring the crack-opening profiles of such Vickers inden...
