Stress intensity factors of an elliptical crack or a semi-elliptical crack subject to tension
International Journal of Fracture, 1974This paper is concerned with the analysis of stress intensity factors of a semi-infinite body with an elliptical or a semi-elliptical crack subject to tension.

A CRITICAL REVIEW OF CRACK TIP STRESS INTENSITY FACTORS FOR SEMI‐ELLIPTIC CRACKS*
Fatigue & Fracture of Engineering Materials & Structures, 1981AbstractSeveral crack tip stress intensity factor solutions have been published for semi‐elliptic, surface breaking cracks in plates subjected to tension or bending forces. These solutions do not agree with each other particularly well and the basis for choosing which one is the best has not been established.

Stress and Fracture Analyses of Semi-Elliptical Surface Cracks
2000The present paper concentrates on both elastic and elastic-plastic finite-element stress analyses of the surface crack in a plate subjected to tension and bending loads. Stress-intensity factor (K) equations that cover a wider range of crack-length-to-width ratios, than those previously developed by Newman and Raju, for various crack-depth-to-crack ...

Analysis of the semi-elliptical crack in the FGM spherical pressure vessels
2023One of the most important analyses in the design of various structures, especially pressure vessels and their safety is the fracture mechanics. One of the important parameters in fracture mechanics is the study of the stress intensity factor of cracks in the tank wall.

Constraint of Semi-Elliptical Surface Cracks in T and L-Joints
Key Engineering Materials, 2006Critical defects in pressure vessels and pipes are generally found in the form of a semielliptical surface crack, and the analysis of which is consequently an important issue in engineering fracture mechanics. Furthermore, in addition to the traditional single parameter K or J-integral, the second parameter like T-stress should be measured to quantify ...

Crack Combination Criteria for Internal Semi-Elliptical Surface Cracks in Pressurized Pipes
Journal of Pressure Vessel TechnologyAbstract Failure of pipes containing multiple cracks is a critical concern, commonly assessed using the mode I stress intensity factor (KI). API 579-1/ASME FFS-1 provides a criterion that allows two closely spaced, semi-elliptical internal cracks in the same plane to be treated as a combined crack for fitness-for-service (FFS ...

A numerical creep analysis on the interaction of twin semi-elliptical cracks
International Journal of Pressure Vessels and Piping, 2008The interaction and coalescence of multiple flaws will significantly influence the service life of components. In this paper, the interaction of two identical semi-elliptical cracks in a finite thickness plate subjected to the remote tension is investigated.

Fracture Analysis of a Semi-Elliptical Surface Crack in Hollow Cylinders
Applied Mechanics and Materials, 2015In this investigation, the weight function method was employed to calculate the stress intensity factors for semi-elliptical surface crack in a hollow cylinder. An uniform stress and a linear stress distributions were used as the two references to determine the weight function.

Fracture analysis for ceramic disk with semi-elliptical crack and pore
International Journal of Precision Engineering and Manufacturing, 2014Crack resistance is important to exam the structures destroyed under static and dynamic load as well as to the ceramic products under extreme mechanical and thermal load. But in addition to the metallic material, ceramic and ceramic composite materials have been pointed out as low resistance referred to a brittle materials form thermal impact.
