Dynamical Stress

Through complex variables function, wave propagation of perforated thin-walled plates is deduced. And it is found out that the dynamical stress concentrates where the concentration parameter vertical to incident orientation is about 1.5, and with the increase of incident wave frequency, holes have less influence on the dynamical stress concentration during wave propagation. With the help of acoustic emission technique, holes do not have much effect on nondestructive test of acoustic emission.

Dynamical Stress

Stress concentrations around a circular cavity in an infinitely extended, thin elastic plate, during passage of plane compressional waves, are discussed. The dynamical stress concentration factors are found to be dependent on the incident wave length and Poisson’s ratio for the plate, and, at certain wave lengths, they are larger than those encountered under statical loading.

Abstract A process is suggested for improving the rubber-cord composite in a radial tire through precision stage-by-stage molding of its parts. This starts by casting an inner elastomeric envelope of the carcass from a liquid oligomer mix. The full molding technology uses acoustic and resonance effects to optimize the degree of order of the structure and of rubber uniformity. The resultant precision tires should have a higher degree of order of both macro- and microstructure than do present commercial tires. Reduced stress concentration in locations that have high failure rates in commercial tires are considered. A new theory, CSSOT, is used for optimizing tires from results of stress-strain cycles.
