The authors regret that Eq. 22 in the above article was incorrectly published. According to the errata “Vivet, M., Cappellini, N., Tamarozzi, T., Blockmans, B., Fiszer, J., Cosco, F., & Desmet, W. (2021). Correction to: Semi-analytic contact technique in a non-linear parametric model order reduction method for gear simulations. Meccanica, 56(10), 2651-2652.” published in August 2021, Eq. 22 is now reproduced correctly. Original: [Formula presented] Corrected: [Formula presented] The reference [34] in the above article should read: [34] N. Cappellini, T. Tamarozzi, B. Blockmans, J. Fiszer, F. Cosco, and W. Desmet, Semi-analytic contact technique in a non-linear parametric model order reduction method for gear simulations. Meccanica, 53(1), (2018) 49-75. The reference [35] in the above article should read: [35] M. J. Puttock and E. G. Thwaite, Elastic Compression of Spheres and Cylinders at Point and Line Contact. Commonwealth Scientific and Industrial Research Organization, Melbourne, Australia, (1969). Therefore, the results obtained by means of Eq. 22 in the above article are modified.
