With the expanding demand on application of magnesium alloys in automotive and aerospace industries, robust methods in fatigue characterization of commercially available magnesium alloys with high specific strength is anticipated. In this paper, rotating bending load controlled tests has been studied on specimens machined from an extrusion piece of AZ31B. Due to asymmetric and anisotropic behav...

According to the characteristics that fatigue study cannot reveal fatigue mechanism and nonlinear influence factors of vehicle driving closed-loop system defects, this paper proposes a driver model inversion method for studying the driver's fatigue diagnosis. Furthermore, the new methods is divided into two steps: 1. using the forecast looks neural network model to build the driver vehicle road...

this paper reviews the current literature examining the pervasive symptom of fatigue experienced in three of the most common degenerative neurological conditions: multiple sclerosis (ms), parkinson’s disease (pd) and post-polio syndrome (pps). the existing literature can be considered under four headings definition and prevalence, type, cause, impact of fatigue. fatigue is a common symptom in d...

Abstract A novel defect-based fatigue model for the prediction of S–N (stress versus number cycles) data points and curves is proposed in this paper. The capable predicting material performance based on defect size location from surface. factor was introduced obtained notch theory, which considers sensitivity as well stress concentration using finite element method. newly developed equation app...

Compassion fatigue is currently the dominant model in work-related stress studies that explain the consequences of caring for others on child-protection workers. Based on a deterministic approach, this model excludes the role of cognition a priori and a posteriori in the understanding of the impact of caregiving or providing social support. By integrating the notion of professional identity, th...

Since appearance of fatigue is a reality in rehabilitation sessions, developing a muscle model that is able to cope with this effect in dynamic contractions is a must. In this paper we attempt to model the effect of fatigue in a Hill type muscle model with weighting sum of joint torques. The promising results will contribute to achieving a generalized model that is able to mold to different mov...

Several studies suggest that when subjects mentally rehearse or execute a familiar action, they engage similar neural and cognitive operations. Here, we examined whether muscle fatigue could influence mental movements. Participants mentally and actually performed a sequence of vertical arm movements (rotation around the shoulder joint) before and after a fatiguing exercise involving the right a...
