Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

Abstract

The snap tension of small-sagged marine cables operating in alternating taut-slack conditions is considered in this paper. The marine cable is suspended at the two ends on the same level. One of the two ends is fixed, while the other is subjected to horizontal excitation. A single non-linear equation of vertical motion of the cable is derived and solved by the Galerkin method. It is found that only the symmetric modes with respect to the mid-span need to be considered. Numerical examples are given and comparisons are made between numerical and experimental results which help to demonstrate the validity of the present method.
