Metal Forming
Elastic and plastic deformation
• Elastic deformation is a change in shape of a material at low stress that is recoverable after the stress is removed.
• This type of deformation involves stretching of the bonds, but the atoms do not slip past each other
• When the stress is sufficient to permanently deform the metal, it is called plastic deformation
• Plastic deformation involves the breaking of a limited number of atomic bonds in the crystal by ....etc

SLIP FORMING.
INTRODUCTION:-
Civil engineering course put more attention to concrete and reinforcement while almost ignoring the major component like formwork. No attention is paid to economic design of formwork. Formwork costs approximately 10% of the total cost of the construction projects but at the same time sheltering/scaffolding involves major capital investment.
The construction industry tod ....etc

A decade ago, riding the devel¬opments in integrated circuit technology and the promises of Moore’s law, the concept of smart dust surfaced. Micro¬scopic devices with sensing, computing, and communication capabilities would be deployed in large numbers in the envi¬ronment to form a bridge between the digital and physi¬cal worlds.1 Along the way, however, major hurdles have blocked this goal. Node energy wasn’t sufficient to communi¬cate across large distances; short-range communications suffered from collisions and retr ....etc

1. INTRODUCTION
Electronic magnetic Forming (EMF) is a process of using electromagnetic forces to form metal, without a tool or punch coming into contact with the part. It is also an ideal process for mechanically joining or assembling dissimilar metal components. An appropriate electromagnetic coil driven by an electric current in the form of a sharp pulse generates the required force for metal forming. A product formed by this process is free from toll marks and heat effects as there is neither to ....etc
