Abstract

Plasticity, or permanent deformation, is one of the most useful mechanical properties of materials. It permits forming of parts, and provides a significant degree of safety in use. The ability to specify plastic properties measured by the standard methods described in this chapter provides industry with a valuable means of controlling their materials of manufacture. These measures also provide the analyst with data for prediction and modeling. However, the current phenomenological basis for plasticity requires a large number of measurements and the development of a more physical basis is badly needed. In this chapter we discuss the physical bases for plasticity and then describe standard methods for measuring plastic properties. Although most industrial needs are being met by existing standards, the appearance of new materials and extreme applications of traditional materials are driving the development of new standard measurement methods. We briefly discuss these new needs and the standards that are being developed to meet them.
