Introduction of STEM for stress analysis in statically determined bodies

Abstract

This article presents a novel approach to the identification of stress states in statically determined bodies. The approach is based on the stress trajectory concept and therefore it is referred to as the stress trajectories element method, (STEM). Three different variants of STEM are presented and some problems associated with these are posed.

Damage zones near excavations: plastic solution by means of stress trajectories

“…This paper is aimed at the development of numerical methods for determination of damage zones in the case of long-wall excavations such as tunnels, well-bores, tabular stopes, etc. Another important motivation of this study is the application of a variant of the stress trajectory element method, STEM, which is currently under development in the Wessex Institute of Technology [1]. The method addresses the problem of stress identification in statically determined bodies by employing stress trajectories.…”
