STRESS INTENSITY FACTORS OF A SEMI-ELLIPTICAL CRACK IN A HOLLOW CYLINDER
Transactions of the Canadian Society for Mechanical Engineering, 2015In this investigation, the weight function method was employed to calculate stress intensity factors for semi-elliptical surface crack in a hollow cylinder. A uniform stress and a linear stress distribution were used as the two references to determine the weight functions.

Fatigue crack growth of semi-elliptical surface cracks
International Journal of Fatigue, 1990Abstract An experimental and theoretical investigation of surface crack growth in 28 mm thick steel plates loaded in pure bending was carried out. The experimental work involved testing plates with initial semi-elliptical surface flaws with aspect ratios of a/c = 0.1, 0.25, 0.5 and 1.0. Crack growth and crack shape development were monitored using AC

An Explicit Weight Function for Semi-Elliptical Surface Cracks
Journal of Pressure Vessel Technology, 1997An explicit weight function which allows determination of the stress intensity factor for a semi-elliptical surface crack under arbitrary loading is proposed. It was derived by the approximate solution valid for an embedded elliptical crack in infinite body, and a suitable corrective function to account for the free surface effect was obtained on the ...

Numerical simulations of semi-elliptical fatigue crack propagation
AIP Conference Proceedings, 2020Residual fatigue lifetime assessment of a cracked structure is a common task for engineering and scientific community. Fatigue crack may appear on the surface or in the initial defect, e.g. pores in weldments. Such a structure needs to be examined, whether is it safe to be operated. Various assessment methods of different difficulties exist.

Fatigue crack propagation of coplanar semi-elliptical cracks in pure bending
Engineering Fracture Mechanics, 1990Abstract The first part of this paper presents stress intensity factor solutions for coalescing coplanar semi-elliptical cracks subjected to pure bending. Crack shapes of “beachmarked” test pieces were modelled using a finite element method and stress intensity factors were obtained using an elastic strain energy method and a displacement ...

Subcritical Crack Growth of semi‐elliptical surface cracks in a turbine rotor
Materialwissenschaft und Werkstofftechnik, 1988AbstractThe subcritial growth of semi‐elliptical surface cracks in the front face of a cylindrical disk was calculated. The disk represents a part of a turbine rotor. The stress intensity factors, which are the basis for the calculations presented here, were given in a former paper [1]. The loads steps considered consist of an inhomogeneous hoop stress

THE PROPAGATION OF NON‐COPLANAR SEMI‐ELLIPTICAL FATIGUE CRACKS
Fatigue & Fracture of Engineering Materials & Structures, 1991Abstract— The results of fatigue tests on specimens containing parallel offset and parallel collinear configurations of multiple non‐coplanar cracks are presented. The fatigue growth of parallel collinear cracks is shown to be significantly affected by crack‐tip shielding and parallel offset cracks are shown to grow almost independently before their ...

Tension and Bending of a Semi-Elliptical Surface Crack
1983Consider the tension and the bending of a finite thickness plate with a semi-elliptical surface crack. Denote the coordinate axes and the geometrical parameters as shown in Figure 1. Preliminary calculations for a flawed semi-infinite solid have shown that the stress intensity factor at the deepest Open image in new window point on the crack front ...

The semi-elliptical surface crack—A solution by the alternating method
International Journal of Fracture, 1976A numerical solution to the three-dimensional equations of elasticity is presented for the problem of a semi-elliptical surface crack in the surface of a finite thickness solid. The alternating method is used to develop the numerical results which incorporate the effects on the stress intensity factor due to the presence of both the front and the ...
