SHAPE MEMORY ALLOYS
1. INTRODUCTION
A shape memory alloy (SMA) (also known as memory metal or smart wire) is a metal that remembers its geometry. After a sample of SMA has been deformed from its original conformation, it regains its original geometry by itself during heating (one-way effect) or, at higher ambient temperatures, simply during unloading (pseudo-elasticity or superelasticity). These extraordinary properties are due to a temperature-dependent martensitic phase transformation from a low-symmetry to a highly s ....etc

Introduction:
Household items made of various kinds of plastic.
Plastic is the general common term for a wide range of synthetic or semisynthetic organic amorphous solid materials used in the manufacture of industrial products. Plastics are typically polymers of high molecular mass, and may contain other substances to improve performance and/or reduce costs. Monomers of Plastic are either natural or synthetic organic compounds.
The word is derived from the Greek past (plastikos) meaning fit for molding, and past ( ....etc

Carbon Fiber Reinforced Polymer (CFRP) is a Polymer Matrix Composite material reinforced by carbon fibers.
The reinforcing dispersed phase may be in form of either continuous or discontinuous carbon fibers of diameter about 0.0004 (10 mkm) commonly woven into a cloth. Similar to fiberglass (glass reinforced polymer), the composite material is commonly referred to by the name of its reinforcing fibers (carbon fiber). The polymer is most often epoxy, but other polymers, such as polyester, vinyl ester or nylon,

ABSTRACT

This seminar is to explain about air powered cars. Air powered cars runs on compressed air instead of gasoline. This car is powered by a two cylinder compressed engine. This engine can run either on compressed air alone or act as an IC engine. Compressed air is stored in glass or fiber tanks

The air is fed through an air injector to the engine and flows into a small chamber, which expands the air. The air pushing down on the piston moves the crankshaft, which gives the vehicle power. The engine has four stage pistons th ....etc

ABSTRACT
The subject gives a brief look on the suitability of composite leaf spring on vehicles and their advantages. Efforts have been made to reduce the cost of composite leaf spring to that of steel leaf spring. The achievement of weight reduction with adequate improvement of mechanical properties has made composite a very replacement material for convectional steel. Material and manufacturing process are selected upon on the cost and strength factor. The design method is selected on the basis of mass production.
From t ....etc

Design and manufacture of White Metal Thrust Bearing

Abstract of the project :
White metal bearings transmit the thrust exerted by shafts rotating at high speeds to the foundation of the machine. White metal thrust bearings were invented by Anthony Michell in 1905. Here, pads are used instead of rollers or balls and the bearing housing is flooded with a hydrodynamic fluid under pressures of about 100 bar in order to minimize frictional losses. This also results in an increased load bearing cap ....etc

ABSTRACT

This paper discusses the basic concepts and current state of development of EUV lithography (EUVL), a relatively new form lithography that uses extreme ultraviolet (EUV) radiation with a wavelength in the range of 10 to 14 nanometer (nm) to carry out projection imaging. Currently, and for the last several decades, optical projection lithography has been the lithographic technique used in the high-volume manufacture of integrated circuits. It is widely anticipated that improvements in this technology will allow it to remain the sem ....etc

Light weight material-Carbon Fibre

Abstract
Steel and other hard construction materials have revolutionized the field of industry. Now, a stage has come that there is a need of a better material to catch up with the growing needs and demands of the modern society. This need has bought up a newer material to the field which is now known as Carbon Fibres.
Carbon fibre is one of the latest reinforcement materials used in composites. It's a real hi-tech material, which provides very good structural proper ....etc

ABSTRACT
Complex tyre behavior is a direct result of the tyre construction. While looking much like a simple rubber doughnut attached to the rim, the tyre construction is vastly more complex, the two main functions of the tyre, is force generation in the road plane and suspension of the vehicle mass. The force generation is made possible by the rubber tread, causing a high friction coefficient with the road surface. The suspension of the vehicle mass is managed by the belt, radial cords and beads. The ....etc
