hydro-forming is a fabrication process that uses a fluid medium to form a piece by using high internal pressure. in tube hydro-forming, a tubular blank is placed between two dies, sealed and pressurized water injected, deforming the tube walls in the cavity form of the dies. exist several typical hydro-forming processes such as t- shapes, cross-shapes and y- shapes. successful hydro-forming dep...

superplastic forming (spf) is a manufacturing process utilized in the automotive industry to produce complex geometry aluminum or magnesium alloy components which cannot be fabricated at room temperature. this paper investigates the effects of the die entry radius and the interfacial friction coefficient on the required forming time and thickness distribution of a superplastic formed part. a co...

the incremental sheet metal forming (ismf) process is a new and flexible method that is well suited for small batch production or prototyping. this paper studies the use of the finite element method in the incremental forming process of aa1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...

Aluminum alloys have a high strength-to-weight ratio and proper anti-corrosion properties that are used in the automotive, shipbuilding and aerospace industries. The major problem with forming aluminum sheets is the low formability of aluminum sheets at room temperature. Therefore, in the present study, warm deep drawing (WDD) of AA5052-O aluminum alloy sheets with a thickness of 1mm was invest...

background and objectives: microbial spoilage of juices and industries related with alicyclobacillus are considerable international issues. this spore-forming bacterium causes changes in juices odor and taste. the isolation and identification of alicyclobacillus contamination in juice producing and packaging industries has an essential role in the prevention and control of this type of spoilage...

Single point incremental sheet metal forming is a sheet metal forming process that forms products without the complex dies and tools with low cost. In this study, the incremental sheet metal forming process has been experimentally investigated on the explosively-welded Al/Cu bimetal sheets. Also, the effects of process parameters, such as arrangement of layer`s bimetal, tool diameter and tool p...

Electromagnetic power, which is one of the fast ways for forming, is used for forming workpieces without having any effect on them. Using it causes the workpieces to reach the minimum back spring and tear; consequently building the equipment like pistons will cost less than before. Electromagnetic power is used for forming Aluminium sheets into V shapes in this study. As the coils connect the m...

the purpose of this study is to investigate the effects of quercetin as an inhibitor of heat shock proteins and hyperthermia on the induced dna damages and colony formation ability of du145 tumor spheroid culture. du145 cells were cultured as spheroids. on day11, spheroids with mean diameter 100 μm were treated with different concentration of quercetin for 24 hours and then exposed to hyperther...

The incremental sheet metal forming (ISMF) process is a new and flexible method that is well suited for small batch production or prototyping. This paper studies the use of the finite element method in the incremental forming process of AA1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...

The conference opened with a talk held by the neuro-biologist, Professor Dr. Michel Imbert (École Normale Supérieure Paris) on the modern image-forming procedures of the neurosciences. Through this method it is also possible to examine moral attitudes and modes of behaviour. A discussion is said to be developing on the manner in which the neurosciences are applying moral concepts – for example ...
