We initiate the study of the vertex-ply of straight-line drawings, as a relaxation of the recently introduced ply number. Consider the disks centered at each vertex with radius equal to half the length of the longest edge incident to the vertex. The vertex-ply of a drawing is determined by the vertex covered by the maximum number of disks. The main motivation for considering this relaxation is ...
In design and fabricate drive shafts with high value of fundamental natural frequency that represented high value of critical speed; using composite materials instead of typical metallic materials could provide longer length shafts with lighter weight. In this paper, multi-objective optimization (MOP) of a composite drive shaft is performed considering three conflicting objectives: fundamental ...
cognitive studies of translation process have recently been awarded a great deal of attention. there exists a psychological angle to almost all translation activities. the present study, thus, deals with analysing the relationships between iranian prospective translators tolerance for ambiguity (ta) and their willingness to translate (wtt). the research was conducted as a mixed methods study, d...
A NURBS-based isogeometric finite element formulation is developed and adopted to the free vibration analysis of finite square and skew laminated plates. Variable stiffness plies are assumed due to implementation of curvilinear fiberreinforcements. It is assumed due to employment of tow placement technology, in each ply of variable stiffness composite laminated plate the fiber reinforceme...
تمرکز تنش در قطعات سوراخ دار مهمترین عامل در هنگام طراحی آن ها می باشد. از آنجا که بر خلاف مواد ایزوتروپیک، تمرکز تنش در صفحات ارتوتروپیک و چند لایه های کامپوزیتی هنوز بخوبی توسعه داده نشده است، در این تحقیق به مطالعه تحلیلی و عددی ضریب تمرکز تنش در صفحات ارتوتروپیک و چند لایه های کامپوزیتی کربن/ اپوکسی و شیشه/ اپوکسی پرداخته شده است. برای مطالعه روش عددی نرم افزار المان محدود انسیس مورد استفاد...
