Estimation 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 کاملStress intensity factor at the hole-edge cracks tips in a finite plate
In the current research work, the problem of fracture mechanics in a plate with a central hole under tensile loading is studied. The stress intensity factors are calculated for a finite plate containing two symmetrical hole-edge cracks. The problem is solved by two different methods, namely the finite element method and the FRANC software analysis. At first the finite element method is used and...
متن کاملStress Analysis at a Bi-Material Interface Crack-tip
The optical methods of Caustics, Photoelasticity and Isopachics for the evaluation of the stress intensity factors and the distribution of the principal stresses at a bi-material interface crack-tip, were proposed. The caustics, isochromatic and isopachic fringes are developed from the stress field which results from a stress function X(r, ). When the crack-tip, which is perpendicular to interf...
متن کاملStress Intensity Factor of Radial Cracks for Rotating Disks and Cylinders using Average Stress Method
This article utilizes the average stress method to obtain the stress intensity factor of rotating solid and hollow disks/cylinders containing a radial crack. It is assumed that the cracks are located radially at center, internal or external radius of the geometry. Results are shown for both of the plane stress and plane strain assumptions and are validated against the known data introduce...
