CHAPTER OBJECTIVES

In this chapter, we will learn how to transform the stress components that are connected with one coordinate system into components associated with a different orientation. This is important because by understanding these transformation equations, you can find out the maximum normal stress and maximum shear stress at a specific point, as well as the orientation of the elements on which they act.

The chapter starts by discussing plane-stress transformation, which is very common in engineering practice. Later, it explains a method for finding the absolute maximum shear stress at a point when the material experiences both plane and three-dimensional states of stress.
