CHAPTER 14
Thick Cylinders and Spheres
14.1 Stresses in Thick Cylinders
Thin cylinders and stresses in thin cylinders were the subject of discussion in chapter 5. It was pointed out there that a cylinder can be regarded as thin if its thickness does not exceed one twentieth of its internal diameter. For thickness of a thin cylinder it was quite reasonable to assume that the hoop or tangential stress remained constant over the thickness. However, in case of a thick cylinder such an assumption is not correct. Practical observations have shown that the hoop stress measured on the surface of a thick cylinder (whose thickness is greater than 1/20 of its inner diameter), is smaller than that calculated by thin cylinder formula or method. This indicates ...
