Introduction to Stress-Strain Relationship and Its Measurement Techniques

Abstract

In this chapter, the basic concepts of strain and the subject of components deformation and associated strain is proposed to be briefly discussed. The strain is a pure geometric quantity so there will be no limitation on the material of the component is required. The significant aspects related to strain and stress-strain relationship briefly discussed in this proposed chapter were as follows: displacement and strain, principal strains, compatibility equations, relationship between stress and strain, two and three dimensional state of stress with respect to strain, stress-strain relationship curve, and overview of various experimental techniques employed for the measurement of stress and strain respectively.
