Effect of Tapered Interference Fit between Impeller and Shaft in Turbo Machines
Journal of Mechanical Engineering, 2018 In Turbo machines, there are many components which are provided with interference to transmit torque and to maintain contact between them. There are transient scenarios where impeller and shaft lose interference and limits the speed of the impeller.

Energy Flux Positivity and Unitarity in CFTs [PDF]
, 2010 We show that in most conformal field theories the condition of the energy flux positivity, proposed by Hofman and Maldacena, is equivalent to the absence of ghosts. At finite temperature and large energy and momenta, the two-point functions of the stress

Structural analysis of long arm excavator boom for optimization performance under maximum breakout condition [PDF]
, 2020 Long Arm Excavators are widely used in the construction site for excavating deep holes or trenches. However, due to the often-severe work conditions, such as large lifting loads, poor ground conditions to sustain the machine’s self-weight, Long Arm ...

Thermal activation of rupture and slow crack growth in a model of homogenous brittle materials [PDF]
, 2003 Slow crack growth in a model of homogenous brittle elastic material is described as a thermal activation process where stress fluctuations allow to overcome a breaking threshold through a series of irreversible steps.

Numerical Analysis of the Influence of Clearance on Stress State and Contact Pressure in Plain Bearings [PDF]
Robotica & Management, 2017 In the analysis of plain bearings by finite element method it is important to model as closely to real state the aspects that influence the stress and contact pressure: the loading mode, the properties of the materials, the lubrication system, the ...

Financial Stress Thresholds and Household Equivalence Scales [PDF]
SSRN Electronic Journal, 2015 This paper relates indicators of household financial stress to household income and expenditure with the objective of identifying household stress thresholds and comparable equivalence scales. A model is proposed whereby households try to absorb income shocks or shifts by shrinking consumption or engaging in consumption substitution, and is applied to ...

Bearing Surface Pressure Distribution of Nut with Cone-form Bearing Surface
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2008 Recently, wheel separation accidents in such vehicles as trucks, buses and passenger cars have drawn a social concern. Explications of their causes and adequate practices of countermeasures for them have been urgently required. In relation to this issue,
