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...

New solutions for static non-rotating thin disks of finite radius with nonzero radial stress are studied. A method to introduce either radial pressure or radial tension is presented. The method is based on the use of conformal transformations. PACS numbers: 04.20.Jb, 98.62.Hr, 02.30.Em

Our aim is to transpose the polarization control by mechanical stress, usually applied to single-mode fibers, to the (TM(01), TE(01), HE(21)(ev), HE(21)(od)) annular mode family. Nevertheless, the quasi-degeneracy of these four modes makes the situation more complex than with the fundamental mode HE(11). We propose a simple device based on periodic perturbation and mode coupling to produce the ...

We report 21 cases of stress injury of the distal radial growth plate-occurring in gymnasts before skeletal maturity. The injury appears to be caused by inability of the growth plate to withstand rotational and compressive forces. Our observations have confirmed that the skeletal age of gymnasts is retarded, which increases the length of time during which the epiphysis is at risk of damage.

In this paper, the problem of calculating the stress intensity factor (SIF) for an orthotropic thick-walled cylinder with a small radial crack subject to internal pressure is considered. The crack is assumed to be an edge crack on the external radius of the cylinder. The stress intensity factor is calculated by superposition of an uncracked cylinder with uniform stress distribution and a cylind...

A case of pseudoaneurysm of right radial artery following transradial coronary angiography is reported. Adequate hemostasis is the key to prevention. Prolonged ultrasonography guided compression of neck of pseudoaneurysm or injection of procoagulants in the cavity of pseudoaneurysm can help non surgical closure.

Conjugated, alkaline hydrolysable ABA (predominantly abscisic acid glucose ester, ABA-GE), which is transported in the xylem from roots to shoots of Zea mays L. plants, has its origin in the root symplast rather than from soil, although it was detectable in soil solution with concentrations up to 30 nM. External ABA glucose ester cannot be dragged with the water flow across the exodermis and th...

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 ...

Stress fractures of the upper limbs are uncommon, and are most often reported as individual cases or small series. In particularly, stress fractures around the wrist are even less common. A stress fracture of the radial styloid process in a judo player was surgically treated, and a favorable treatment outcome was obtained. A 16-year-old adolescent boy experienced pain in the right wrist, with n...
