The ferromagnetic material launcher is a coilgun that launches magnetically permeable material. This technology has both military and scientific applications such as defense, space launches, train travel, etc. This project uses principles of magnetic fields, electric circuitry, computer programming, and mobile application software in order to achieve the project goals; these being the FML capab...

In this paper, bending analysis of concentric and eccentric beam stiffened square and rectangular plate using the meshless collocation method has been investigated. For detecting the governing equations of plate and beams, Mindlin plate theory and Timoshenko beam theory have been used, respectively, with the stiffness matrices of the plate and the beams obtained separately. The stiffness matric...

Ring-stiffened flat bottom tanks are widely used in many industries for the storage of liquids, such as oil, fertilizers, water, sewage and sludge. Material efficiency is achieved by combining thin plates with ring-stiffeners. When bin covered a dome or cone roof, high meridional forces due to live snow loads may trigger axial buckling shell. Ring stiffeners beneficial, not just against wind, b...

در این مقاله یک روش تحلیلی برای تحلیل ارتعاشات آزاد پوسته مخروطی کامپوزیتی fml ارائه شده است. برای روابط اساسی از فرضیات پوسته های نازک استفاده شده و معادلات دیفرانسیل حاکم بر مسئله بر پایه اصل همیلتون استخراج شده است. برای حل معادلات حاکم نیز روش تحلیلی گلرکین به کار گرفته شده است. همچنین به منظور بررسی اثر شرایط مرزی مختلف بر پاسخ فرکانسی پوسته، از توابع تیر برای تقریب شکل مود ها در این مقاله...

Fibre metal laminates (FMLs) have appeared as the most suitable materials for shipbuilding, aeronautical and aerospace applications due to their superior mechanical properties over traditional materials. In this paper, degradation in flexural and impact properties of glass fibre/epoxy composite (GF/E composite) and stainless steel glass fibre/epoxy fibre metal laminate (SS FML) due to hygrother...

Abstract   Fiber-metal laminates (FMLs) are new type of composite materials which could improve defects of traditional composites in ductility, formability, impact and damage tolerance. Drawing behavior of a thermoplastic based FML was investigated consisting of glass-fiber reinforced polypropylene composite laminate and aluminum AA1200-O as the core and skin layers, respectively. The effects o...

The aim of this study is to investigate effects of isothermal aging on mechanical properties of fiber metal laminates (FMLs) and glass/epoxy composites. For this purpose, both materials were fabricated using the wet lay-up manufacturing technique under vacuum pressure. Both the glass/epoxy composites and the FML specimens were then subjected to isothermal aging (130°C, dried air) for up to 5 we...
