Hydroforming (or hydramolding) is a cost-effective way of shaping malleable metals such as aluminum or brass into lightweight, structurally stiff and strong pieces. One of the largest applications of hydroforming is the automotive industry, which makes use of the complex shapes possible by hydroforming to produce stronger, lighter, and more rigid unibody structures for vehicles. This technique is particularly popular with the high-end sports car industry and is also frequently employed in the shaping of aluminium tubes for bicycle frames, Hydro ....etc

This topic is devoted to the analysis of the mechanical behavior of filament-wound pipes. The process of filament winding makes it possible to produce rotating parts made of composite material containing polymers reinforced with long fibers. Most of the time, this process consists in winding a fiber tow coated with a thermosetting polymeric matrix around a mandrel, and thus covering the entire mandrel after successive passages. Following a polymerization phase, the mandrel can be removed in order to get only the composite structure. In certain ....etc

1. INTRODUCTION

Hydro forming is a relatively new process, which uses water pressure to form complex shapes from sheet or tube material. Design studies suggest that automobiles can be made much lighter by using hydro formed components made of steel. Structural strength and stiffness can be improved and the tooling costs reduced because several components can be consolidated into one hydro formed part.
As the automobile industry strives to make car lighter, stronger and more fuel efficient, it will continue to drive hyd ....etc

ABSTRACT
The need for lighter, stronger, more rigid vehicle structures will increasingly require complex hydroformed structural tubes to increase strength, and decrease weight, cost and part count. This effort will increase the use of high strength, low alloy (HSLA) steel, in place of SAE 1006/1008 or 1010 steel. Traditional hydroforming techniques require the higher elongation of the latter materials. An alternative tube hydroforming process has been d ....etc

1. INTRODUCTION
A heat pipe is a simple device that can quickly transfer heat from one point to another. They are often referred to as the superconductors of heat as they possess an extra ordinary heat transfer capacity & rate with almost no heat loss.
The development of the heat pipe originally started with Angier March Perkins who worked initially with the concept of the working fluid only in one phase (he took out a patent in 1839 on the hermetic tube boiler which works on this principle). Jacob Perkins (descendant ....etc
