forming limit curve (flc) is an important tool for evaluation of formability of sheet metals subjected to different loading. free bulge of aluminume tubes has been investigated numerically to obtain flc. to verify the numerical results one experimental setup has been manufactured which has the ability of controlling the internal pressure and axial feed. in this study, time and zone of bursting ...

A fast, easy anastomotic technique with a high patency rate would facilitate the development of microvascular surgery. This article describes a new nonsuture method of end-to-side microvascular anastomosis using a soluble polyvinyl alcohol (PVA) T-shaped tube as an internal stent and plastic adhesive. Two kinds of T-shaped tubes were used: Type I tube had a short straight tube connected to a lo...

Product design in the early stages requires a more quantitative process to ensure that simulation study's outcome will meet expectations. The purpose of this study was determine whether manufacturing software package could effectively evaluate and validate conceptualised blank tooling manufacture sizeable complex- shaped aluminium alloy aircraft panel using die sheet hydroforming. Blank tool co...
