Tensile Introduction

CHAPTER 1 Introduction to malleable analyzeing TENSILE TESTS argon performed for several reasons. The results of malleable tests ar used in selecting cloths for engineer applications. ductile properties oft are include in stuff and nonsense speci?cations to ensure quality. Tensile properties ofttimes are mensural during study of new materials and processes, so that different materials and processes offer be compared. Finally, pliable properties often are used to predict the behavior of a material beneath forms of loading otherwise than uniaxial tension. The strength of a material often is the primary concern. The strength of interest may be quantityd in terms of either the sieve necessary to case appreciable plastic deformation or the maximum stress that the material loafer withstand. These measures of strength are used, with appropriate reprove (in the form of safety factors), in applied science design. Also of interest is the materials ductility, which is a measure of how much it can be deformed before it fractures. seldom is ductility interconnected directly in design; rather, it is included in material speci?cations to ensure quality and toughness. Low ductility in a tensile test often is accompany by outset resistance to fracture under other forms of loading.

Elastic properties as well may be of interest, exclusively special techniques must be used to measure these properties during tensile testing, and more accurate measurements can be made by ultrasonic techniques. This chapter provides a outline overview of some of the more weighty topics associated with tensile testing. These include: ? ? Tensile specimens and test mach ines Stress-strain curves, including discuss! ions of elastic versus plastic deformation, yield points, and ductility ? confessedly stress and strain ? Test methodology and data compendium It should be noted that succeeding chapters contain more little information on these topics. intimately notably, the following chapters should be referred to: ?
