Assessment of the Existing Models to Estimate the Fatigue Life under both Multiaxial in Phase and 90° Out of Phase Loading Conditions

Engineers have a range of methods to estimate the fatigue life under multiaxial conditions. Each of these predictive methods is generally subjected to restrictions, related to the inherent simplified assumptions. The objective of this paper is to evaluate the validity of commonly used multiaxial fatigue criteria for different multiaxial loading conditions. The best criterion is identified throu...

Investigating the Visual Fatigue in VDT Operators in the Banks of Qasr-e Shirin (Kermanshah-Iran)

Background & Aims of the Study: Due to the increasing use of computers in the administrative and social structure of Iran, it seems that, in the near future, eye and body symptoms caused by computer work will become one of the most important health issues in our society, and threaten the health of the workforce and consequently, lead to significant financial and industrial losses. The aim of th...

Finite element analysis of fatigue damage in passenger-car diesel engine cylinder head under cyclic thermo-mechanical loadings

In this article, the thermo-mechanical fatigue lifetime of the cylinder head of a passenger-car diesel engine has been estimated. At the first stage, stress and strain distributions in the cylinder head have been calculated using the two-layer visco-plastic model, available in the ABAQUS software. The calibration of the model was performed, using correlating of simulated hysteresis curves and l...

Is visual fatigue changing the perceived depth accuracy on an autostereoscopic display?

In this paper, a subjective study is presented which aims to measure the minimum perceivable depth difference on an autostereoscopic display in order to provide an indication for visual fatigue. The developed experimental setup was used to compare the subject’s performance before and after 3D excitation on an autostereoscopic display. By comparing the results to a verification session with 2D e...
