in this paper, a novel technique on friction aided deep drawing using tapered blank holder divided into eight segments is proposed to overcome defect of friction aided deep drawing using four segments tapered blank holder technique. a taper blank holder is designed to be of two parts: stationary part with 5 degree taper angle and moving parts divided into eight tapered segments. the main functi...

all the producing and assembling processes exert residual stress on the pieces that may lead to structural failure. therefore, calculating the residual stress in such structures has been common in recent years. in this article, distribution of temperature and residual stress resulting from arc welding in three-pass butt joint in p91 austenitic stainless steel pipes is calculated and estimated u...

Friction plays an important role in creating damping mechanism structures.In this paper a study was conducted to analyze coulomb friction andfrictional energy dissipation with stone blocks single degreeof freedom system by discrete and continuum modeling finite element-based software ABAQUS. Discrete approach wasused study. It found that both approaches gave similar results.

Abstract Experimental investigation of RCC beam provide an important understanding on its flexural properties. The stages involved from the design to casting, curing, testing and interpretation results is time consuming involves economy labour. To reduce above said challenges, numerical seems be alternate without involvement money Preliminary equation which are provided by basic experiments con...

because of high strength to weight ratio, 6061 aluminum has many applications in different industries like automotive and aerospace industries and can help to reduction of fuel consumption. forming limit diagram (fld) is a useful method for sheet metal formability identification. whereas calculation of forming limit diagram by experimental tests is expensive and time consumption, in the present...

The main purpose of this article is the structural analysis of a composite blade of a selected helicopter. In this study, the stresses on rotors' blades caused by centrifugal forces, lift, drag and torque are analyzed. The governing equations of the structure behavior and solving processes were carried out by MATLAB software, and simulation is carried out by ABAQUS software, and they are compar...

Abstract The behavior of box-shaped columns under heating is investigated. For this purpose, the various sections thin-wall were modeled and verified in different temperature ranges by ABAQUS software. results research showed that increasing thickness leads to increase buckling stability column change. Since will be better than thinner climate change because modulus elasticity. solid have hollo...

Abstract: Hybrid III dummies are among the most frequently used dummies in both industry and academia for vehicle crash safety. Abaqus is one of most widely applied finite element codes in the world. To meet the needs of crash safety analysis and to exploit the potential of the Abaqus/Explicit code, a family of HIII dummies, including HII 50th male, 5th female and 95th male dummies, were develo...
