Chapter 11Introduction to Finite-element Analysis

11.1 Introduction

In Chapter 1 we learned the four stages involved in general engineering analyses, with Stage 2 being idealizing actual physical situations for the subsequent mathematical analysis in Stage 3, and Stage 4 being interpretation of analytical results. Idealization of actual physical problems is necessary in most cases of engineering analysis so that analytical tools that engineers have acquired and are available can be used. Idealization of geometry and loading and boundary conditions is frequently ...
