با افزایش روز افزون مصرف قطعات TWB در صنعت خودرو سازی درک رفتار شکل پذیری آنها برای بدست آوردن محصولاتی با کیفیت بالا از این نوع ورقهای مرکب در فرایندهای شکل دهی به ویژه فرآیند کشش عمیق نیز اهمیت بیشتری می یابد به این منظور در این تحقیق فرایند کشش عمیق بلتکهایی از نوع TWB که از ترکیبهای ضخامتی مختلف تشکیل شده اند و دارای موقعیت های مختلف خط جوش اند و تیزبلتکهای ساده اجزای پایه آنها بای ایجاد قط...

Single crystals of caesium tantalate(V), Cs(10)Ta(29.27)O(78), were obtained as a serendipitous product in a welded tantalum ampoule by a blank reaction of CsBr and bis-muth subnitrate [Bi(5)O(OH)(9)(NO(3))(4)] with the container material. The crystal structure of the title compound is made up of a three-dimensional framework constituted by two types of layers, viz. (Ta(6)O(15))(n) and (Ta(3)O(...

This paper proposes an advanced method for contrast enhancement of capsule endoscopic images, with the main objective to obtain sufficient information about the vessels and structures in more distant (or darker) parts of capsule endoscopic images. The proposed method (PM) combines two algorithms for the enhancement of darker and brighter areas of capsule endoscopic images, respectively. The hal...

Welding method and its parameters has an important effect on the formability and mechanical properties of tailor welded blanks(TWBs). In this study gas tungsten arc welding(GTAW) is used to joint aluminum TWBs. Aluminum TWBs consist of 6061 aluminum sheets with different thickness of 1mm and 2mm. Main parameters of GTAW consist of welding current, pressure of shielding gas, welding speed and di...

For the t → W+b decay mode, an intensity-ratio equivalence for two distinct Lorentzinvariant couplings is shown to be a consequence of symmetries of tWb-transformations. Explicit tWb-transformations, A+ = M ASM , P ASM , B ASM connect the four standard model’s (SM) helicity amplitudes, ASM (λW+, λb), and the amplitudes A+ (λW+ , λb) in the case of an additional chiral-tensorial-coupling of rela...

Tailor-made blanks are sheet metal assemblies with different thicknesses and/or materials and/or surface coatings. A monolithic sheet can be machined to make the required thickness variations that is referred as tailor machined blanks. Due to the thickness variation in tailor machined blanks, laser bending of these blanks is more complicated than monolithic plates. In this article, laser formin...
