A simplified form of the bound in terms of a material reference stress is shown to be independent of the form of the creep constitutive relationship subject to certain conditions which are satisfied by a wide range of creep laws. This result is used to

It is shown that while some components are subjected to a measure of primary loading, stresses are mainly induced by thermal effects which give rise to both creep and fatigue damage. It is arg

It has also been recognised that for the severe operating conditions advantage would have to be made of the hardening properties of the metal. In the paper

Two important concepts, introduced in earlier papers, are developed further — that of the locus or surface of elastic critical points at which the creeping structure collapses, and that of the long-term elastic critical loa

Studies in Computational IntelligenceStructure calculations on refractory alloys at variable temperature must take into account the microstructural instabilities which may lead to important hardening. This paper describes an experimental and numerical study involving the following points:

Smart Innovation, Systems and TechnologiesGeneralised models are well-known in elasticity and plasticity as a means of simplifying the stress analysis of geometrically complex structures. It is the purpose of this paper to restate this philosophy for creep mechanics.

Advances in Creep Mechanics,A review is made of the advances which have been made in creep mechanics in the last decade. Both deformation and failure are considered and an attempt has been made to indicate the influences that the recent advances have had on the development of design rules.
