Nanotribology and Nanomechanics Including Nanomechanical Properties, Adhesion and Surface Roughness With Application to Magnetic Storage Hard Disk Drives
In the second part of this work, a systematic approach considering the above basic elements was used to investigate impact-induced contact damage of Head Disk Interfaces during operational shock. A contact mechanics based analysis with consideration of mechanical properties and thickness of various sub-micron thick surface layers, effect of adhesion, effect of roughness and flash temperature was performed to study the impact between slider corner and disk surface. The above contact mechanics based analysis was validated by a 3-dof, dynamic, thermomechanical finite element analysis.
