On the accuracy of the pressure measurement film in Hertzian contact situations similar to wheel-rail contact applications

Experimental investigations and finite element simulations on the measuring error of Prescale pressure measurement films of the mono-sheet type 'S' were done with perfect Hertzian contact bodies in contact situations similar to the wheel-rail contact. The sources of the systematic error were identified and quantified. (C) 2014 Elsevier B.V. All rights reserved.
