The model proposed by Decuzzi et al. [1] has been modified here to estimate the variation of b–perturbation growth rate—with V—relative sliding speed. It has been verified that the perturbation with the lowest critical speed has also the highest growth rate, and that low frequency perturbations are less critical than high frequency perturbations, at fixed critical speed. Therefore, when comparing perturbations with identical critical speed, those with higher wave numbers are responsible for more intense thermomechanical damages. Also, for perturbations with wave number smaller than the critical mcr, the temperature increases with m; vice versa for perturbations with wave number larger than mcr the temperature decreases with m. A reduction in thickness ratio a1/a2 between friction and metal disks has the effect of increasing the temperature and growth rate. An approximate formula for the temperature variation with time has been derived for a linearly decreasing engagement speed.</mods:abstract><mods:originInfo><mods:dateIssued encoding="iso8061">2003</mods:dateIssued></mods:originInfo><mods:genre>Article</mods:genre></mets:xmlData></mets:mdWrap></mets:dmdSec><mets:amdSec ID="TMD_eprint_23260"><mets:rightsMD ID="rights_eprint_23260_mods"><mets:mdWrap MDTYPE="MODS"><mets:xmlData><mods:useAndReproduction><p xmlns="http://www.w3.org/1999/xhtml"><strong>For work being deposited by its own author or their nominees in the public archive:</strong> In self-archiving this item/collection of files and associated bibliographic metadata, I grant e-Prints Soton the right to store them, to make them available online without charge in accordance with the access setting selected and after the expiry of any embargo period stipulated to make them available publicly.
