in iran we already use laminate tubes only in cosmetics industry. laminate tube manufacturers via using the most modern technology of the world, faced with the laminate tube market being saturated in cosmetics industry for packaging the cosmetic creams and toothpaste. but considering the great food market and therefore laminate tube features such as beautiful packaging, ease of use for the fina...
tube hydroforming (thf) process is used to produce the complex components from the initial cylindrical tubes. in this paper, t- shape component was formed using a tube hydroforming machine and the residual stresses of hydroformed tube was determined by hole drilling method. subsequently, the thickness distribution and residual stresses of final tube were investigated using experimental and fini...

Abstract The analyzed electrohydraulic servo valve is jet pipe type, is one of the mechatronics component used for precision flow control application. It consists of several precision and delicate components. For the analysis the jet pipe assembly of servovalve is identified and conducted a direct-solution steady-state dynamic analysis to study the response of the system for harmonic excitation...
The goal of electron linear accelerator project in institute for research in fundamental sciences(IPM) is to build its components as many as they can in Iran. This accelerator is a traveling wave type. Investigations show that there are various techniques in forming and connecting the accelerating tube cavities. The shrinking method applied for constructing the accelerating tube is selected bas...
effect of nano titanium oxide, nano zinc and multiwall carbon nano tube on yield and yield components of green gram was carried out in kohkiloyeh-boyrahmad province, iran with 30 degrees 45' n and 50 degrees 44' in 2013 growing seasons. the experiment was arranged as factorial in a completely randomize block design with three replications, treatments including: four concentrations (ze...
the basic strategy of reduce the ductility demand and related concentrated tensions at moment resistance connections is reduce the section of the beam at connected region to column. by this method plastic hinge done at the reduced cross section and this local reduction decreases the demand of the components of connection. on this basis, in present study a new beam-to-column moment connection wi...
