OS01W0265 Photoelastic investigation of modified hertz contact theory

Abstract

A series of photoelastic experiments were performed in this paper to demonstrate the feasibility of modifying the classical Hertz contact theory to meet the practical needs. It was found that the match between the experimental and theoretical results was indeed improved by adjusting the contact half-length. Correction factor for accounting the boundary effects was also nvestigated. Furthermore, the replaced superposition method was successfully implemented to determine the contact stresses around a near-edge circular hole in a semi-infinite plate.
