in this paper we show that if q is a power of a prime p , then the projective special linear group psl(2, q) and the stabilizer of a point of the projective line have maximum sum element orders among all proper subgroups of projective general linear group pgl(2, q) for q odd and even respectively
afinite element model is developed for simulation of the curing process of a thick axisymmetric rubber article reinforced by metal plates during the molding and cooling stages. the model consists of the heat transfer equation and a newly developed kinetics model for the determination of the state of cure in the rubber. the latter is based on the modification of the well-known kamal-sourour mode...
metal forming processes, compared with machining ones, reduce production steps and increasemanufacturing speed in addition to saving raw material. in this paper, forming process of column ofa steering mechanism is investigated by finite element analyses and experimental tests; andoptimum die design parameters are found. forming process parameters including die opening angle,bearing length, clea...
حرکت یک وسیله نقلیه ریلی تحت تاثیر کرنشهای الاستیک هرتز که در سطح تماس ریل و چرخ ایجاد می شود قرار دارد. این کرنشها وقتی با حرکت پیشروی و چرخشی چرخ ادغام می گردند باعث بروز انحرافات جزئی در حرکت چرخ می شوند که آن را خزش نام گذاری کرده اند. برای ایجاد خزش معینی در چرخ نیروهای تماسی در سطح تماس چرخ و ریل باید به مقدار مشخصی برسند. هر چند این نیروها در سرعتهای کم باعث اصلاح مسیر چرخ به مسیر عادی م...
frictional shear stress is usually determined by utilizing the coefficient of friction or the constant friction factor models. the present study deals with finite element analysis of double cup extrusion process to determine the relationship between constant friction factor (m) and coefficient of friction (µ), since the metal flow in this process is very sensitive to frictional conditions. ther...
To solve crack problems, some coupled methods have been developed in recent years. Most of these methods have some shortcomings such as the need for a transition region. The finite element and enriched element free Galerkin methods are widely used for this class of problems. In order to take the advantages of these methods while avoiding the disadvantages, it is essential to follow solution app...
Forced vibration analysis of plate is growing research subject as plates are used for manufacturing many mechanical structures. The analytical solutions have been found for plates with specified mass and stiffness but for the plates with uncertain mass and stiffness are studied very limitedly. The uncertain parameters play an important role in the design of practical mechanical system. It becom...
