Thin-Walled Structures with Structural Imperfections






INTRODUCTION
This book is about the influence of structural imperfections on the static response of thin-walled shells and plates.

This introductory chapter explains wha.t we understand by struc- tural imperfections (Section 1.1) and how they arise in real thin-walled structures. There are several ways to classify imperfections, some of which are shown in Section 1.2. This is followed by examples in some common shell structures, where imperfections have been found to be ,

important (Section 1.3). The reasons why we may need to understand the influence of imperfections are discussed in Section 1.4, with ref- erence to practical situations in which an interested party needs to pursue this kind of investigation. Finally, Section 1.5 contains an out- line of the book, stating the scope, objectives, contents, and possible uses of the work.
