A comprehensive elastic-plastic finite element analysis is presented for the axisym-metric problem of a frictionless rigid sphere indenting a half-space with a harder and stiffer layer. The indenter is modeled by contact elements, thereby avoiding a

When the flying height is below 5 nm, some physical phenomena that can be ignored for higher flying sliders need to be included in the modeling equations. Another challenging issue is the unavoidable asperity contact problem. It is known that zero sp

An approximate two‐dimensional theory is used to study the electromechanical behavior of face electroded, circular, piezoelectric (PZT) disks of the type used in transducers. Solutions are obtained for the voltage generated in both free and forced

Several recent developments in ink-jet printing have motivated numerous scientists to investigate the details of the breakup process of liquid jets emanating from nozzles. The entire January 1977 issue of the IBM Journal of Research and Development w

We study the recently derived reflection coefficient for plane waves in a liquid that are incident on the liquid–solid interface of a solid half‐space, which consists of a single layer of one elastic material bonded to a substrate of a different

We study the motion of a magnetic recording disk drive read/write slider as it drags in contact with thin film and particulate media disks. The out-of-plane displacement of the slider is measured with a laser-Doppler vibrometer (LDV), and its in-plan
