Hydroforming patch technology for damaged screen pipes is designed based on tube hydroforming technology, and the methods determining forming pressure range defects are selected according to process. The model established technical demand parameters pipe repair. From mechanical properties of material digital–analog comparison analysis formability, it found that determiners formability (such as ...
Abstract Hole flangeability is a measure of edge formability or local formability, and it important for forming processes like stretch flanging. sheet metals evaluated by determination hole expansion ratio (HER) using standard test (HET). In the present work, numerical experimental investigation has been carried out on 1.6mm thick AA6061 alloy sheets. The material model plays an role in accurac...
Nowadays new research area focused on hybrid inorganic/organic fibres materials based on bacterial cellulose and inorganic nanoparticles paid attention of many researches. It is well known that homogeneously dispersed nanoscale inorganic particles in a polymer matrix improve the mechanical properties of the resulting nanocomposites. Hybrid materials containing metal or semiconductor nanoparticl...
Ink-jet printing is a method for directly patterning and fabricating patterns without the need for masks. To achieve this, the fluids used as inks must have the capability of being stably and accurately printed by ink-jetting. We have investigated the inter-relationship between ink-jet printability and physical fluid properties by monitoring droplet formation dynamics. The printability of the f...
This paper deals with design method for structure of injection mold fabricated by Metal Laser Sintering, which is one of the rapid prototyping technologies. This technology provides mold with more sophisticated function and improvement of formability and productivity. To realize structure of mold with these advantages, the method has been developed by following processes : (1)Specifying importa...
