the crankshaft is one of the most critically loaded components as it experiences cyclic loads in the form of bending and torsion during its service life. its failure will cause serious damage to the engine so it’s important at the time of design to verify fatigue strength. more challenges in crankshaft design due to increasing vehicle payloads, lower weight requirement, higher efficiency and lo...

background : the purposes of this study were to examine the impact of chemotherapy treatment on jordanian cancer patients’ fatigue and to correlate their fatigue with selected sociodemographic variables at the beginning of treatment and after four weeks of treatment. methods : this was a single group quasi-experimental correlational design study that enrolled 43 patients diagnosed with cancer w...

Introduction Fatigue is the structural damage that leads the components of a wind turbine to sudden brittle failure when it suffers cyclic loading [15]. As the size of wind turbines is growing, fatigue loads become more and more significant for the design of major structural components. Concerning fatigue in a wind turbine tower, the fore-aft tower foot bending moment is considered as the most ...

For the fatigue design of a large scaled welded structure, the readily accessibility of various engineering tools is required for the static, fatigue, dynamic analysis and parametric study. In this paper, a multi-agent system is suggested for the development of distributed, open and intelligent design system. The developed design system is applied to assess cumulative fatigue damage on the weld...

Four different limit states formats for the fatigue design of reinforced concrete and prestressed concrete structures are described and compared within the context of simple second level reliability theory. All four formats lend themselves to reliability treatment but the cycle format appears to be the most useful at the present time, given the limited quantity of design data available on the f...

Interactive genetic algorithms are effective methods applied into the conceptual design of car console in order to better cater to the customer’s individualized demands for product design. In traditional interactive genetic algorithms, users’ fatigue problem restricts the population size. We propose individual fitness estimation method based on artificial neural network to reduce user fatigue p...
