Stress Intensity Factors For Single Cracked Pressurized Cylinder

PLASTIC INTENSITY FACTORS FOR CRACKED PLATESt

An elastic-plastic analysis is performed for two problems relevant to fracture mechanics: a semi­ infinite body with an edge crack in a far out-of-plane shearing field and an infinite plate under plane stress conditions containing a finite line crack in a remote tensile field. Amplitudes of the dominant singularity in the plastic region at the crack tip, the plastic stress and strain intensity ...

Justification and Imfroveme~ of Kienzler and Herrma~s Estimate of Stress Intensity Factors of Cracked Beam

Kienzler and Hernnan recently showed that good and remarkably simple approximations of the stress intensity factors of cracks in beams can be obtained by bending theory estimations of the strain energy release as the crack is widened into a band of finite width. Their method has been based on equating this energy release to the energy release rate due to crack length extension, which has been p...

Stress Intensity Factors in a Hollow Cylinder Containing a Radial Crack

In this paper an exact formulation of the plane elasticity problem for a hollow cylinder or a disk containing a radial crack is given. The crack may be an external edge crack, an internal edge crack, or an embedded crack. It is assumed that on the crack surfaces the shear traction is zero and the normal traction is an arbitrary function of r. For various crack geometries and radius ratios, the ...

Calculation of Stress Intensity Factor in Rotary Cracked Disks with Central Hole by Using Emulator Technology

In this paper, the crack growth and variations of stress intensity factor in rotary disks with central hole is studied. For modeling and analyzing samples, the FRANC2D software is used and to predict stress intensity factor, DACE emulator (Design & Analysis of Computer Experiments) is used and, at the end comparison between results of modeling and results of simulator has been done. The emulato...
