CHAPTER 6

Mechanical Behavior

The tensile test is one of the most useful techniques for describing the key mechanical properties of engineering materials. (Sergey Ryzhov / Alamy.)

LEARNING OBJECTIVES

After studying this chapter, you should be able to:

1. 1. Analyze a stress-versus-strain curve for a typical metal alloy and report the four main mechanical properties: modulus of elasticity (E), yield strength (Y.S.), tensile strength (T.S.), and ductility (100 × ϵ_failure).
   2. Define the various terms associated with stress-versus-strain measurements, such as elastic deformation, plastic deformation, specific strength, strain hardening, toughness, and ...
