Abstract

This article deals with the study of transversely isotropic elastoplastic behaviour in a mechanical loaded rotating disk by using transition theory and generalised strain measure. Magnesium material disk requires higher value of angular speed to yield at the inner surface as compared to the disk made of beryl material. With the effect of mechanical loading, angular speed also increases at the inner surface of the disk made of magnesium/beryl. Upon the introduction of mechanical loading, the rotating disk made of beryl material requires maximum radial stress at the inner surface as compared to disk made of magnesium material. The beryl material disk is more convenient than that of magnesium material.

Keywords: stresses, disk, beryl, magnesium, angular speed
