On The Contradictory Values of Stresses in the Area of Contact of Two Parallel Rollers
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 7
Abstract
The paper provides explanation of contradiction between the results obtained with analytical and numerical methods for the problem of the maximal shear stresses and their depth in the area of contact of two parallel circular cylinders (rollers). It is claimed that the aforementioned contradiction is usually unreasonably connected with imperfection of the numerical method in theory and practice of contact calculations. It is proved in the analytical way as well as in the numerical one that the main reason for the contradiction to exist is significant misstatement of the role of the curvature of the contact elements by the solutions within the limits of the classical theory.
