Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Many faults grow by linkage of smaller structures, and damage zones along faults may arise as a result of this linkage process. In this paper we present the first numerical simulations of the temporal and spatial evolution of fault linkage structures from more than 20 pre-existing joints, the initial positions of which are based on field observation. We show how the constantly evolving geometry and local stress field contribute to fault zone evolution. Markedly different fault zone trace geometries are predicted when the joints are at different angles to the maximum compressive far field stress ranging from evolving smooth linear structures to producing complex 'stepped' fault zone trace geometries. We show that evolution of the complex fault zone geometry is governed by 1) the strong local variations in the stress field due to complex interactions between neighbouring joints and 2) the orientation of the initial joint pattern with respect to the far field stress.
