SMART MATERIALS AND SMART STRUCTURES

SMART MATERIALS AND SMART STRUCTURES

ABSTRACT

The entire world is changing at a faster rate and to cope up with this change applying modern technology is a must to live up to the standard. Infrastructure plays a vital role and this is possible by construction of smart structures.

A smart structure speaks about how the construction works can be done effectively and efficiently. The four scarce resources man, machine, material and money are to be utilized very effectively to achieve the best result, i.e. to complete the construction works with the right quality taking into considerations the safety to living at top most priority. These things can be made into reality by making use of computers and digital signal processing

An earthquake is one of the most terrifying phenomena that nature can dish up. We generally think of the ground as “rock solid” and completely stable. An earthquake can shatter that perception instantly, and often with extreme violence.

Up until relatively recently scientists only had unsubstantiated guesses as to what actually caused earthquakes. Even today there is still a certain amount of mystery surrounding them, but have scientists have a much clear understanding.

There has been enormous progress in the past century. Scientists have identified the forces that cause earthquakes, and developed technology that can tell us an earthquake’s magnitude and origin.

This paper deals mainly with the approach of MR fluid during earthquake. In addition to the above; the examples of the application of smart materials in the bridges are also explained. Now a day, smart structures are very useful in structural health monitoring & damage detection. Finally, we conclude that the application of smart materials will definitely enhance the quality of our life.
