Chapter 2

Briefing on Mechanics for Solids and Structures

2.1 Introduction

The concepts and classical theories of the mechanics of solids and structures are readily available in numerous textbooks (see, for example, Timoshenko, 1940; Fung, 1965; Timoshenko and Goodier, 1970; Xu, 1979; Hu, 1982). This chapter serves to introduce these basic concepts and classical theories in a brief and easy to understand manner, so that readers are well prepared to appreciate the application of the finite element method to solve solid mechanics problems.

Solids and structures are stressed when they are subjected to loads or forces. The stresses are, in general, not uniform, and lead to strains, which can be measured using strain gauges, or even observed as either ...
