The stress analysis of grinding mills in the early 1970s was generally based on simple beam theory. Incorporation of more detailed stress distributions due to stiffness discontinuities and the stress concentrations due to various design details, such as head to shell joints and man-holes, was being undertaken by some vendors ( Cornford, 1972 ).
