this paper develops an analytical method to calculate seismic bearing capacity of a strip footing, which is located on a slope reinforced with rows of pile. the resistance of passive pile is determined based on normal and shear stress of the soil around the pile, which is then compared to other analytical methods. this comparison indicates an acceptable agreement. the variants of the study incl...

In this study carburizing and boronizing processes were applied to powder metallurgy steel specimens and the mechanical and tribological properties of the substrate and coatings were evaluated under various process conditions. The specimens, made from industrial test pieces, were carburized in a powder pack for a duration of 2-5 hrs at 850-950 ˚C. Similar specimens were pack boronized for 4 hr...

For a reciprocating compressor of household refrigerators, a direct analogy between the pipe flow network and the electric circuit network has been utilized to set up a mathematical model for oil supply system. Individual lubrication elements of the oil supply system, such as propeller-installed oil cap, oil galleries, radial oil feeding holes, spiral oil grooves, and various sliding surfaces h...

Porous asphalt (PA) pavements are widely employed in areas with wet climates. As particle enhancement inclusions mastic, mineral fillers play essential roles improving the performance of PA pavements. This study developed a coupled multiscale finite element (FE) model, involving mesostructure mixture and pavement. Four types mastic properties were four (Granodiorite, Limestone, Dolomite, Rhyoli...

The thermal contact resistance between the balls and the inner and outer rings of an angular contact ball bearing is investigated. It is assumed that the bearing sustains thrust, radial, or combined loads under a steady-state temperature condition. The shapes and sizes of the contact areas are calculated using the Hertzian theory. The distribution of internal loading in the bearing is determine...
