This paper investigates the ultimate tensile behavior of bolted stiffened T-stub connections using experimental, numerical, and analytical methods. The monotonic tests were carried out on sixteen with different parameters to investigate failure mode, yield line distribution, key mechanical properties them. results showed that distribution pattern along center bolt holes changed increase thickne...

in this paper, the mean value of strain energy density criterion has been used to predict the critical fracture load in specimens with u-shaped notch under bending loads. an equation for calculation of averaged strain energy density in this zone has been presented. bending loads under mode i have been considered. two cases have been studied: 1) the control volume only includes the semicircular ...

the main purpose of this study is to determine welfare impacts of trade liberalization on maize market. for this purpose, we used from time series data for the period 1961/2009 and estimated domestic supply, domestic demand and import demand for maize. results of estimation showed that price elasticity of supply and demand is 0.32 and -0.25, respectively. then, by means of these elasticities, w...

1.Introduction Following several methods of some past publications, among these we refined an important idea that related queries could be derived from queries submitted within the same session. As the browsers not just provide the previous queries but more informations,so we could use these informations to build a expert database for a special user, base on the database ,we could analysis some...

This paper presents an insole FSR (Force Sensing Resistor) to dynamically detect weight variations in an exoskeleton system. The proposed methodology is intended for tasks of lifting and lowering heavy weights with an industrial exoskeleton to substantially reduce spinal loads during these manual handling activities. Instead of extensively placing high-dense force sensors by covering the whole ...

The noise and vibration of large oil-immersed reactor is usually controlled reduced by using high-strength pretensioned steel rods to fasten iron cores. But the effect uneven temperature increase in on pretension relaxation rarely discussed previous literatures. A combined fastening device rod disc spring designed conduct experiment this paper. And three-dimensional (3D) finite element model de...

The intermodular connection between modules plays a vital role in the overall performance of modular structures. separation column and is possible due to absence links (welding or bolting) since limited space available modules. This study proposed self-locking joint be used steel structure, connecting columns with without need extra behavior subjected monotonic load was evaluated using finite e...
