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

The scaled boundary finite element method (SBFEM) combines the advantages of finite element method (FEM) and boundary element method (BEM). Therefore, it is considered as a powerful tool to analyse the soil-structure interaction problems. In this research, this method is extended to include Biot's coupled consolidation in order to deal with fully saturated soil as two-phase medium. The general 2D dynamic analysis case, including body forces and surface tractions in different media in the frequency domain, is formulated. In addition, Chebyshev pseudospectral method is introduced for solving the FE coupled consolidation equations.
