A Numerical Solver for the Wheel-Rail Contact Subjected to Combined Loads
Crețu, Spiridon; Bărbînță, Constantin-Ioan (Universitatea ”Dunărea de Jos” din Galați, 2009)A working algorithm, able to be incorporated into a computer code, has been developed to solve the stress state in the general case of non-Hertzian contacts. Brent’s method has been involved to find the contact point for ... -
On the Effect of Spectral Characteristics of Roughness on Contact Pressure Distribution
Crețu, Spiridon; Bălan, Mihaela Rodica; Urzică, Ana (Universitatea ”Dunărea de Jos” din Galați, 2009)In the first part of the paper, the matrix containing the roughness heights is obtained by a linear transformation of the Gaussian input matrix, the coefficients of the transformation matrix being found as solutions of a ...
