FLOW BEHAVIOR OF MOLTEN METAL IN ALUMINUM LFC PROCESS
The effects of gating system and pattern geometry on the metal flow in the lost foam casting (LFC) process have been investigated using glass covered mold and video recording system. Unlike convectional casting process, the type of the gating system showed little effect on fillability in lost foam, but pattern thickness had large effect on mold filling. The mold filling behavior seems to be con...
متن کاملEffect of Morphology on Rheological Properties of Ethylene-vinyl Acetate Copolymer (eva) (containing 40 Wt% Va Content) Nanocomposites
The combination of Ethylene-vinyl acetate copolymer (EVA) with nanoclay has wide commercial applications (such as packaging films and cables), which depend on the vinyl acetate contained in the main chain. As the vinyl acetate content increases, the copolymer presents less crystallinity and different mechanical behavior. EVA with 40 wt% vinyl acetate content (EVA40)/ organoclay nanocomposites w...
متن کاملMechanical behavior of ethylene vinyl acetate copolymer (EVA) used for fabrication of mouthguards and interocclusal splints.
In the present investigation, an experimental dental arch model fabricated in epoxy was assayed in Kratos universal testing machine to study the mechanical behavior of ethylene and vinyl acetate copolymer (EVA) in the form of mouthguard for sports and flat plate. The following variables were considered: thickness (3 and 4-mm plates), temperature (room and mouth temperature) and presence/absence...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
