Abstract:
The work described in this thesis was designed to extend the investigation of Dr.S.Bhattacharya, who showed that the creep of a variety of metals, at room temperature and under constant stress, could be satisfactorily described by the equation:- l)::; a tk. It was hoped to be able to determine the effect of stress on this equation. In addition to this, preliminary work on creep under fluctuating stresses is described in Appendix 1. Previous work pertinent to the investigation is reviewed. It is concluded that, of the two most common equations, the Andrade equation and the power-law, the latter is the more generally applicable. Metallographic evidence seems to support the common association of each of the two terms of the Andrade equation with a recognisable mechanism of creep. It is suggested, however, that such an association involves certain theoretical difficulties.
