Abstract
Rocking stability of a rigid prismatic block standing on a rigid base subject to a simple harmonic acceleration function is still an important dynamics problem, in which energy loss is often not treated accurately enough. The energy loss at impacts during rocking is here examined. The stability for various slendernesses and sizes of a rocking block is assessed numerically, where an improved coefficient capable of estimating the size effect is considered. A number of relevant cases are validated experimentally, with a specially designed set of well-controlled and documented rocking benchmark tests on a shaking table system.
期刊介绍：
Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
