ANALYSIS OF RAIL - WHEEL CONTACT STRESSES USING FINITE ELEMENT METHOD IN COMPARISON WITH ANALYTICAL SOLUTION
Main Article Content
Abstract
present in a wide variety of mechanical components. In
addition, contacts usually act as stress
concentrations, and are thus probable locations for mechanical failure. Some of the most
typical mechanical failures involving contact include: fretting, fretting fatigue, wear, fret
ting
wear and false brinelling.
