Tensile Introduction

CHAPTER 1 Introduction to tensile Testing tractile TESTS argon performed for several reasons. The results of whippy tests are used in selecting cloths for engineering applications. ductile properties a great deal are overwhelmd in stuff speci?cations to ensure quality. ductile properties ofttimes are careful during development of new materials and processes, so that different materials and processes offer be compared. Finally, tensile properties oft are used to predict the behaviour of a material at a lower place forms of loading other than uniaxial tension. The forcefulness of a material frequently is the primary concern. The authorisation of sake may be metric in terms of both the sieve necessary to fiber appreciable plastic torture or the maximum dialect that the material loafer withstand. These preventions of strength are used, with appropriate blame (in the form of safety factors), in engineering goal. Also of amuse is the materials ductileness, which is a measure of how much it posterior be deformed earlier it fractures. Rarely is ductility interconnect directly in design; rather, it is included in material speci?cations to ensure quality and toughness. base ductility in a tensile test often is accompanied by beginning resistance to fracture under(a) other forms of loading.

Elastic properties as well may be of interest, but special techniques must be used to measure these properties during tensile testing, and much straight measurements can be do by ultrasonic techniques. This chapter provides a outline overview of some of the more important topics associated with tensile testing. These include: ? ? Tensile specimens and test machines Stress- emphasis curves, including discussions of elastic versus plastic deformation, yield points, and ductility ? confessedly stress and strain ? Test methodology and info compendium It should be observe that subsequent chapters contain more little information on these topics. Most notably, the following chapters should be referred to: ?
