โœฆ Synopsis

A simply supported shaft with a transverse crack is investigated for its vibrational characteristics. The local flexibility due to the presence of the crack is represented by a (6 \times 6) matrix for six degrees of freedom in a short shaft element which includes the crack. A finite element analysis is carried out for free and forced vibrations. The possibilities of backward whirl due to the crack are presented. The severity of the fluctuating bending stresses in shafts due to the crack is associated with the backward whirl of the rotor.

A diagnostic method of determining the position and size of a transverse open crack on a stationary shaft without disengaging it from the machine system is investigated. The crack is modelled as a joint of a local spring. To obtain the dynamic characteristics of a stepped shaft and a multi-disc shaf

In this paper, a method is presented for predicting the three-dimensional dynamic response, shear stresses and structural intensity of torsional vibration in a "nite shaft with stepped cross-sections. The series expansion techniques is employed to express the dynamic responses and shear stresses in

## Abstract Recent studies have demonstrated that stress may increase the fluctuating asymmetry of teeth and limbs in laboratory animals. The present study investigates the effects of heat on such parameters. Pregnant laboratory rats are exposed to temperatures of 33ยฐC during gestation. Increases i
