Failure and root cause analysis of vehicle drive shaft
Engineering Failure Analysis, 2019This paper investigates the failure mode and root cause of drive shaft failure in a vehicle through examination of the macroscopic and microscopic morphologies of the fracture surface, the chemical composition, metallographic analysis, and mechanical ...

Performance of screw–shaft pile in sand: Model test and DEM simulation
Computers and geotechnics, 2018A screw–shaft pile is a bored, cast-in-situ, displacement foundation solution. This study examines the performance of axially loaded screw–shaft piles by laboratory model tests, digital image correlation, and discrete element modelling.

Trichoscopy in Hair Shaft Disorders.
Dermatologia clinica, 2018Trichoscopy allows analyzing the structure and size of growing hair shafts in their natural environment in children and adults. The method replaces light microscopy, which requires pulling of multiple hairs for investigation.

Numerical study of natural ventilation in urban shallow tunnels: Impact of shaft cross section
Sustainable cities and society, 2018Natural ventilation with vertical shafts uses less energy and occupies less space in a tunnel, compared to mechanical ventilation. Therefore, this natural ventilation mode has been adopted in more and more urban tunnels. This study analyzed the influence

This paper addresses the heat transfer coefficient (HTC) associated with the hollow-shaft rotor cooling of a traction motor. In such a hollow-shaft cooling system, the coolant is made to flow through the shaft hole in order to cool the rotor.

Investigation on the critical shaft height of plug-holing in the natural ventilated tunnel fire
International journal of thermal sciences, 2018In order to study the plug-holing of vertical shaft with different fire-shaft distance in road tunnel, a series of numerical simulations about tunnel fire were carried out. The results have shown that the smoke layer thickness under the ceiling increases

The femur is a long bone that extends from the hip to the knee. At its proximal end is the head, neck, greater and lesser trochanters, at the distal end a metaphyseal flare to the medial and lateral condyles. The femoral diaphysis (shaft) is bowed anteriorly. The femur is a tubular bone, which gives it strength to withstand axial loading; this enables
