Chul Hee Lee, Auteur ; Melih Eriten, Auteur ; Andreas A. Polycarpou, Auteur |Asymmetric height distribution in surface roughness is important in many engineering surfaces, such as in constant velocity (CV) joints, where specific manufacturing processes could result in such surfaces. Even if the initial surfaces exhibit s[...]

Chul Hee Lee, Auteur ; Andreas A. Polycarpou, Auteur |To analyze the contact between two spherical bodies with different radii of curvature, the three-dimensional (3D) Hertz theory for elliptical contact is typically used. When the two contacting bodies have high conformity, such as the case for ba[...]

Raja R. Katta, Auteur ; Andreas A. Polycarpou, Auteur ; Sung-Chang Lee, Auteur |Scratch-related magnetic signal degradation can occur during magnetic storage hard disk drive operations when the read-write heads contact the spinning multilayer disks. To investigate this phenomenon, controlled nanoscratch experiments were per[...]

Raja R. Katta, Auteur ; Andreas A. Polycarpou, Auteur |A contact mechanics (CM) based model of a fixed-length rigid cylinder impacting a homogeneous elastic-plastic homogeneous body was developed and includes an improved method of estimating the residual depth after impact. The nonlinear elastic beh[...]

Xi Shi, Auteur ; Andreas A. Polycarpou, Auteur |As the areal density of magnetic disk storage continues to increase and head-disk spacing decreases, contact between the recording slider and the rotating media becomes imminent. In order to predict contact forces, fly-height modulations, and of[...]
