Mechanical Properties

5.1 INTRODUCTION

The mechanical behaviour of a material reflects the relationship between its response (deformation) to an applied load (or force) such as strength, ductility, hardness, stiffness and toughness. These are known as mechanical properties. These properties play a vital role in the analysis and development of structures, machines and engineering and commercial products. These components are subjected to natural or applied loads under varying conditions of temperature and environment. Determination of mechanical properties through various tests is of utmost importance to design engineers. There are two types of tests: destructive and non-destructive. This chapter explains the destructive test, in which the ...
