Three-Dimensional Stresses
CHAPTER OBJECTIVES
There is no structural component which is only two-dimensional. Only to simplify the analysis of stresses, a component is considered under plane stress condition, i.e., negligible thickness. In actual practice, there is effect of thickness on the stresses of an element. Even in a bar subjected to uniaxial load, presence of a notch creates triaxial stresses in the vicinity of notch. Therefore, three-dimensional stresses in a body will be studied in this chapter. Students will learn about:
Components of stresses on three orthogonal planes of a body.
Normal and Shear stresses on a plane inclined to three orthogonal planes.
Strain components on three orthogonal planes.
Plane stress and plane ...
