Abstract: Yung-shih (Tony) Wang has presented an equation for the breaking loads from a multiyear pressure ridge on a conical structure. The three distances that define the position of the plastic hinges were determined numerically by minimizing the rate of work with respect to the distances. An exact solution for Wang's equation is given in this paper, and is approximated with a cubic equation.
